Excerpt from The Mechanism of the Brain: And the Function of the Frontal Lobes
In 1881 I had occasion to observe a remarkable feature relating to dogs which had undergone extirpation of the sigmoid gyrus of both sides. I was struck by the fact that there was an appreciable difference in behaviour between those animals in which the extirpation had been limited chiefly to the sigmoid gyrus, affecting either the whole or a part of that convolution, and other animals in which the operation had involved more than the sigmoid gyrus, having extended forwards, in front of the presylvian fissure. I had performed these operations with the special object of elucidating, as far as possible, the problem of functional compensations within the cerebrum and the anatomical limits within which cortical compensation was possible. The experiments had perforce to be numerous, and it was also necessary that I should keep the animals under observation for a long time after the Operations. Thus it came about, apart from any stimulus to further investigation to be found in the scanty literature of the subject, that there arose in my mind a strong desire to attack the problem of the function of all that cerebral area which is situated in front of the presylvian fissure, a function that was wrapped in utter darkness. Afterwards came the great discussion between Hitzig, Munk, and Goltz, and thenceforwards I applied myself seriously to this particular inquiry.

Paperback. Zustand: New. Print on Demand. This book combines experimental investigations with psychological and anatomico-pathological research to posit that the higher mental processes are located not in the post-frontal, but in the frontal lobes of the brain â" a belief that had been previously challenged by many physiologists. The author reviews the evolution of the nervous system, advancing a naturalistic thesis that every psychological complex involves a neural engram â" that all mental events involve physiological correlates. Moving on to the behavior of monkeys from whose brains the frontal cortex has been ablated and their relative lack of consciousness as the analogue of what we commonly mean by the word, the book ventures into an exploration of the nature of consciousness. Concluding with a discussion of the part which intellect, sentiment, and human sociality have played in the advance of civilization, this book pushes the boundaries of our understanding of the relationship between the human mind and brain.
