CHAPTER I: WHAT IS THE USE OF A BRAIN?

ALL mental operations take place in and through the superficial grey matter, or "cortex," of the brain. Organic life, nutrition, circulation, excretion, secretion, motion, in fact all vital functions can be carried on without the cortex of the brain ; but the manifestation of the intellectual and moral powers, the affections, and propensities or instincts of self-preservation, cannot take place without it. Provided that the cortex of the brain be not affected, all the other portions of the system may be diseased, or separately destroyed, even the spinal cord may become affected, without the mental functions being impaired. Of course if the heart, the medulla oblongata, or some other vital part be injured, death will precede any such experiment. If, on the other hand, the superficial grey matter of the brain becomes compressed, irritated, injured, or destroyed, the mental functions get partially or totally deranged or become wholly extinct. When the compression of the brain is removed, as in the case of an indented skull, or a tumour, or the extravasated blood or accumulated pus is evacuated, or the cerebral inflammation allayed, consciousness and the power of thought and feeling return.

We think and feel, rejoice and weep, love and hate, hope and fear, plan and destroy, trust and suspect, all through the agency of the brain-cortex. Its cells record all the events, of whatever nature, which transpire within the sphere of existence of the individual, not merely as concerns the intellectual knowledge acquired, but likewise the emotions passed through, and the passions indulged in. We can only manifest our intellectual aptitudes, moral dispositions, and tendencies to self-preservation, through the mechanism of brain with which we happen to be endowed, and according to the sort of experience we have accumulated. Hence though the primitive mental powers and fundamental anatomical parts of the brain of all men are the same, we all vary according to the mental predispositions and brain-types we have inherited and the early education we received. The cerebral mechanism is, by dint of its original structure, apt or otherwise for certain pursuits, moral and animal tendencies, hence our actions are the result of the inherited organic constitution, past education and experiences, and the circumstances which surround us. Grapes will not grow on the thistle, but we can improve or debase the organisation we inherited. There is in every one of us an individuality which we are conscious is not due to training or to circumstances, and which, however these may modify it, cannot be entirely eradicated. Originality is kept down by transmitted tendencies, which give colour to all our deductions from experience, and, as it were, framed us in the pursuit of knowledge and manifestation of character. We do not all see things alike, nor does nature awaken in all similar tastes and sympathies. Not only is it true that certain persons distinguish themselves at a very early age by extraordinary attainments, but certain manifestations of good or bad temper, and other feelings, occur in very early life, before any adequate cause is apparent. The underlying impulses \which shape man's character have in great measure come to him as inheritances of parental virtues or vices, and they are the capital with which he and circumstances have to work, and which, in spite of both, must always impart colour to his every act.

Parents, therefore, who indulge chronically in evil tendencies incur great responsibility. It is not the idea that is inherited, for there are no innate ideas, but the disposition. During the process of making new records, that is during the individual life of the brain, its organic memories and inherited habits get revived, and these modify the manner of the new recording.

Though the brain may be represented as a unit yet it contains innumerable centres with afferent and efferent fibres, and fibres which connect them all together, a network of intricate organic paths, along which a stimulus started may travel in countless, but not indefinite, directions. These centres represent organically every minute detail of knowledge and experience, they register every definite observation and thought, and every process of reasoning with which the individual has at any time made himself familiar ; they represent every sentiment and emotion, every affection and passion, and indeed every one of those mental processes which are needful for the display of what constitutes human character. All the fundamental kinds of psychical activity are carried on in more or less distinct parts of the cerebral hemispheres. There is the same order in the organisation of the cerebrum as in every other organ, the same physiological division of labour, in which all organisation consists. See Plate i for a diagrammatic representation of the direct brain-fibres, radiating from the centre to the circumference.

The brain is more complicated, and the convolutions more distinct and numerous, as we ascend the scale of the animal kingdom. The essential differences obtaining in the encephalic structure correspond to decided differences in its functions, and the complexity of the structure is proportionate to the number of aptitudes and propensities displayed. What can be the purpose of the difference in the organisation of the brain in different animals, unless it be the difference prevailing in relation to the variety of their instincts. If it be admitted that their instincts are hereditary, then it must also be admitted that they are due to some peculiarity in the brain-structure. One species of animals is endowed with mental powers, in which another is deficient, a fact that would be inexplicable, did not each particular cerebral function reside in a particular portion of the brain. Suppose I should enquire of my readers how it happens that certain species of animals are devoid of the sense of smell, or some other sense, whilst they are in full enjoyment of the rest. They would find no difficulty in such a phenomenon. The functions of each sense, I should be told, require a particular apparatus, and certain species may not possess one or the other of them. But, if they admitted only one organ, through which all the senses executed their functions, the absence of one or more in any animal would be inexplicable. Now let the like reasoning be applied to the primitive mental powers, the manifestation of which depends on the brain. There is scarcely any species of animal which does not enjoy certain aptitudes and propensities not to be found in other species. The unwieldy beaver and the nimble squirrel are both admirable architects ; the dog, the docile, intelligent and unwearied companion of man, has no skill in building. The horse and bull have not the bloodthirsty propensities of the weasel and the falcon. The sparrow and the turtle-dove do not utter the sweet notes of the nightingale. Sheep live in flocks and rooks form communities ; the fox, the eagle, and the magpie, dislike the confinement imposed on them by the care of their young, to which they impatiently submit during some weeks only. The swallow, stork, fox, etc., are faithful in their attachment to a single mate ; the dog, so susceptible of affection, the stallion, and the stag, gratify their desires with the first female of their species which they meet. Thus natural history, from beginning to end, exhibits in each species of animals different propensities and aptitudes. Does not, then, the conclusion necessarily follow that the distinctive propensities and aptitudes of these animals are relative to different cerebral parts ? Were the brain the single and universal organ of them all, each animal ought to possess them all indiscriminately. Or if the brain, as some suppose, subserved to the intellect alone, it would be no longer possible to conceive that man is elevated by superior intellectual faculties above all other animals, to a far greater extent than the mere size and weight of the entire brain would warrant. But, if it be supposed that each primitive mental power, like each particular sense, depends on a special cerebral part, it is not only conceivable that any one animal may be destitute of a certain cerebral part possessed by another, but likewise that all animals generally may be lacking in certain encephalic parts with which man is solely endowed.

The intellect, moral sentiments, affections, and propensities are so essentially different, that there must be separate centres for them. No one supposes for an instant that the same bundle of nerve-cells and fibres which is employed in intellectual effort is that also through which the emotion of anger gets manifested.

The mental powers prevailing in every individual of the same species exist in very different degrees ; a circumstance only to be explained by the different development of the several parts through which these powers are manifested. The mastiff, bulldog, pug-dog, grey-hound, etc., are distinguishable from each other, not by their shape only, but also by their individual character, though they all have the character pertaining to dogs generally. Individuals of the same variety likewise differ much from each other, which would be impossible were each primitive quality not dependent on a particular centre. Men possessing first-rate talents of a certain order are sometimes perfectly insignificant in every other respect. Genius is in well-nigh every instance partial, and limited to the exaltation of a few mental powers, which could not be the case were the organ of mind single. Moreover, genius not unfrequently appears at so early an age as to put study or training, as a producing cause, entirely out of the question. No one will deny that it is a natural gift. Have you not noticed that prodigies are quite as childish as other children in everything but the talent by which they are particularly distinguished. In partial idiocy the individual is exceedingly deficient in most of the intellectual powers, and frequently in some of the moral sentiments, and yet may possess a few of them in considerable vigour. Thus an idiot may have a talent for imitation, for drawing, or for music, and be incapable of comprehending a single abstract idea ; or he may show a hoarding inclination, a destructive tendency, or the sexual instinct, and yet manifest no other power to any perceptible extent.

Were the brain a single organ, then the innate dispositions of each man would be similar. But if the main and accessory convolutions of the brain be appropriated to different mental powers, then does every modification of character depend on a different degree of development attained by these particular parts of the brain, and their varying degree of activity. There are no two skulls, nor two brains alike in their configuration, nor are the characters of any two individuals found exactly to correspond. Look at Plate 2 and compare the narrow top-head of the rebel-chief Galishwe with the broad upper region of Dr Earth, the missionary.

There is a natural inequality in men. No two are alike in character. There prevails among individuals an infinite variety of intellectual endowment, of moral sentiment, affections, and instincts of self-preservation. The force and order of the impulses differ in every one. Some young folk, though lacking in intelligence, possess an astonishing faculty for learning by heart ; others again remarkable for their intelligence have great difficulty in committing to memory. So with grown-up men. One will remember dates, another localities, a third individuals, and a fourth events. One lacks wit and gets angry at all mirth and fun, another is deficient in dignity, another

REV. C.G. BARTH, D.D.  (Missionary)  

There is a natural inequality in men. No two are alike in character. There prevails among individuals an infinite variety of intellectual endowment, of moral sentiment, affections, and instincts of self-preservation. The force and order of the impulses differ in every one. Some young folk, though lacking in intelligence, possess an astonishing faculty for learning by heart ; others again remarkable for their intelligence have great difficulty in committing to memory. So with grown-up men. One will remember dates, another localities, a third individuals, and a fourth events. One lacks wit and gets angry at all mirth and fun, another is deficient in dignity, another dislikes children. One expects to find the enjoyment of life in wealth, another in power, a third in rank, a fourth in fame, while not a few are found to seek it in a mere round of excitement. Some folk are noted for their cruelty, others for their courage, others again for their slyness. Then there are persons who never had any friends and do not want any. Again, a little observation shows us that some men, apart from all training, have a decided capacity for certain pursuits. One man excels in history, another in geography, a third in mathematics. Some become great musicians, others eminent painters, others distinguished poets, or actors. Most of us are wholly devoid in some mental power : some are baffled by arithmetic, some have no skill for drawing, some are a dead-weight at music. Such mental quality is vouchsafed to one and denied to another. Each has a predilection, or a more decided talent, for a particular pursuit. There is, then, in every man something which he does not derive from education, and which even resists all training. We follow the line of least resistance, that is to say, the line along which our most active dispositions and abilities drive us. From his very childhood does a man show the character which will distinguish him in adult years. He is haughty or humble, prudent or careless, affectionate or cold, harsh or kindly, because it is in his nature to be so ; in other words, because his brain organisation is so constituted. Every physician should be able to point out these innate capacities and dispositions, and be capable of planning for instructors rules for each pupil, in order to perfect the good qualities and correct the evil ones, and to put the youth in a state to employ his powers in a manner useful to himself and society at large. Seeing the vast difference there is in the shape of heads, it is surprising that it has hitherto received so little attention. Compare, for instance, the portraits of Fox and Scott, Plate 3.

Education will act on the pupil in proportion to his innate mental powers, it will sharpen his existing aptitudes and dispositions, but it will not supply any new one ; it cannot transform a Newton into a poet, nor a Milton into an astronomer. Of course it is not enough to be endowed with special mental powers, to have inherited a particular brain-structure. They must be roused into activity by external impressions, and subsequent exercise and application are indispensable to acquire facility and skill.

Some of man's primary mental powers take higher range, and some lower, but all are useful and necessary in their proper place. Happiness signifies a gratified state of them all. The gratification of a mental power is achieved by its exercise. To be agreeable, that exercise must be proportionate to the development of the aptitude or disposition ; if it be insufficient, discontent arises, and its excess produces weariness. As long as a particular brain-centre contains an abundance of stored up nerve force, it responds pleasurably to a stimulus ; if the natural appetite or disposition be too freely exercised, the nerve energy that keeps it active is used up and it ceases to respond. This is what the voluptuary discovers to his cost. Hence, to achieve complete felicity is to have all the mental powers exercised in the ratio of their respective development.

PLATE 3.

CHARLES JAMES FOX, 1749-1806 (Statesman).
Notice large perceptive region. He was quick to observe and had a retentive memory.
Notice the breadth of head across the ears. He had a passionate temper, was addicted to vice, and was an invective speaker, using vigour but no adornment.
There was no romance about him, nor would the type of head lead us to expect it.

SIR WALTER SCOTT, 1771-1832 (Author, Poet).
Of immense imagination. Great lover of the romantic.

It is a law of our nature that when a thing has been done once, it is more easily achieved a second time, and with each repetition becomes ever more easy, till at length it grows to be natural and there is an appetite or a craving for it. The force of early habits is such that they generally determine our practice through life, and when once built up and strengthened are seldom if ever to be broken. Hence the necessity for constantly guarding against evil habits and against the practice of indulging the animal nature as opposed to the moral and spiritual ; even the first beginning should be guarded against, the one first act that renders the repetition thereof more easy. The aim and purpose of the teacher then should be to render easy the doing of right and the doing of wrong difficult, and by want of practice unnatural and impossible. Whatever makes a good or bad action familiar to the mind renders its performance by so much the easier.

Exercise of mind implies exercise of brain. When any part is exercised, an afflux of blood takes place towards it, attended with heat and increased action ; and if this be carried too far, or be persisted in too long, morbid excitement will take the place of healthy, and derangement of function will follow. A morbid state of any brain centre may be induced either by causes acting directly upon its function or by causes immediately affecting the substance of which the centre is composed.

The existence of such evidence, as I have adduced in my book on " The Mental Functions of the Brain," to the effect that injury to the head affects one or more of the mental powers, according to the locality on which it was inflicted, while in other respects the individual remains perfectly sound, can only be explained on the principle that the several portions of the cerebral hemispheres have different functions allotted to them. So unregardful have physicians been of this fact that many of them deemed it quite unnecessary to state in their clinical reports in which region of the skull the injury was inflicted. But from the number of cases accurately observed and recorded, it is evident that injury to the brain beneath the parietal eminence, the angular and supra-marginal convolutions, leads to Melancholia in different degrees ; that injury at the base of the temporal bone, the middle part of the inferior temporal convolution, leads to a manifestation of irascibility, which may end in Violent Mania, and so on ; and that when the effects of the injury are removed in such wise as by lifting up an indented bone, the patient recovers his mental equilibrium. From other cases it becomes apparent that after injury in one particular region the " sense of relation of tones," one of the factors of the " musical faculty," may be lost, while in another region the memory of figures and power of calculation may disappear, leaving the other intellectual powers normal. These facts have not hitherto been observed sufficiently, but when they come to be so the localisation of mental functions will make rapid advance.

Similarly it has been observed that irritation of the frontal cells is characterised by an acceleration of the intellectual processes of perception, association, and reproduction, giving rise to a rapid flow of ideas; and that softening of the same part leads to dementia, whereas irritation of the parietal, occipital and temporal area affects chiefly the emotions and propensities, often leaving the intellect quite unclouded. That emotional display which is seen after injury or disease of the frontal lobe is merely the weakening of the intellectual control, which leaves the predominant bias of the individual free to exercise itself. In certain forms of poisoning, too, such as by Alcohol, the highest mental powers are paralysed first, thereby depriving a man of the controlling power over his natural tendencies. Hence some intoxicated men get dejected, others gay ; some talk foolishly, others are eloquent ; some become effusively benevolent, others furiously maniacal, and so on. All these facts point to there being a congeries of centres in the cortex of the brain, not merely for the purely intellectual operations, but also for the emotions and propensities.

Experiments made on the inferior animals by means of electricity can throw no light on the mental functions of the brain. It is only possible to observe those functions which come under the direct observation of the senses, symptoms which are motor in character, and which cannot be traced back to any volitional act of the subject. But if each portion of the nervous system governing movement be an independent local centre of power, it is a fair inference that each portion of the nervous system governing the mental acts is likewise an independent centre of power.

In favour of there being distinct centres in the brain is furthermore the fact of its arterial supply. The frontal lobes are fed by the internal carotid arteries, the parietal and occipital lobes by the basilar artery, the union of the two vertebral arteries. The inosculation in the Circle of Willis I believe to have been overrated. The vaso-motor nerves of these two areas are also differently derived. Those of the posterior area spring from the inferior cervical ganglion, into which run the fibres ascending from the abdomen, by the greater splanchnic nerve. On the other hand the carotid arteries derive their vaso-motor supply from the middle and superior cervical ganglia.

Last, but not least, we have the observations of numerous investigators showing that certain regions of the cerebrum are distinguished from other regions by broad differences in structure. Not only does the structure in different convolutions assume to a greater or less extent a variety of modifications, but even different parts of the same convolution may vary with regard either to the arrangement or the relative size of their cells. These structural differences must be correlated with some difference of function. The group of cells whose function is purely intellectual cannot possibly have the same construction as a group of cells whose function is purely emotional. The two may be united by association fibres, so that one may rouse the other, but the function of each group of cells must be distinct.

Though we may speak of a centre, it is understood that as there are two hemispheres of the brain, every centre is two-fold, and to this fact may be due those few instances in which a particular centre got injured or destroyed without a loss of any mental power being discoverable. This is especially the case in accidents to the right half of the brain, which seems to be less active than the left. Where the two halves are unequal, I have frequently observed that the right represents what the individual is by nature, i.e. his inherited organisation, and the left what he has made of it.

The more highly developed the mental powers, the more connected will the various centres of the brain become by means of intricate channels of the freest intercommunication. Though the centres themselves are distinct, all of them are interunited, and the activity of each depends on its relation to the others. It is therefore a mistake to look for a protuberance of brain-matter, or a bump on its outer-covering, the skull. No one centre is competent to manifest itself by itself. Each acts as a portion of the brain to modify the general result of cerebral action. It is through this solidarity and interdependence that no portion of it can be injured or exhausted without its interfering in some way with the functions of the other portions. There is, however, a great difference between saying that the various brain-parts exert a mutual influence, and saying that each part does not perform its own particular function. The positions of the centres are not accidental, but are governed by fixed principles. One centre fuses with another, hence neighbouring centres are related in their mental manifestation. Centres are of a higher character, and of later acquisition, in proportion as they occupy a higher locality in the brain. Thus the highest mental powers will be found farthest from the base of the brain, for the rigid base of the skull does not admit of much extension. On the other hand, the vault of the skull remains open in two places at least for some time after birth, and even in later life is still capable of an increased arching to make room for increased brain-mass. The lowest and most indispensable mental powers-for instance, the instincts of self-preservation common to men and animals-will be found at the base of the brain ; the highest mental powers, and of later acquisition- for instance, the moral sentiments-are at the top of the head, in the superior part of the frontal convolutions.
