Excerpt from The Psychological Monographs: Symptomatological Differences Associated With Similar Cerebral Lesions in the Insane; Variations in Distribution of the Motor Centers To account for the individual variations in both mental and nervous diseases, the psychoses and the neuroses, it has been most easy and quite satisfying to presuppose functional and struction'al [differences of the lesions, because of our relative ignorance of many of the functions and of the anatomical con nections of parts of the nervous system. This is specially true when we deal with lesions or disease of the cerebrum and the basal ganglia. Within recent years, however, there has been growing the realization that a minute lesion in one part of the brain may give rise to a symptom or to a collection of symptoms which is exactly the same as that resulting from a similarly minute lesion in a second or a third portion of that organ. If we liken the cerebral mechanism to the stations and lines of a telephone or a telegraph plant we may readily understand how this can be. If the emissive element or the transmitter be broken or destroyed it is not possible to transmit the message in a par ticular direction or to a given point. The function is abolished. But we must also keep in mind that a similar abnormal condition of function arises ii, instead oi. Having a lesion of the emissive element, there be a break in any part of the conducting line. Such an injury or a disease may be close to or far from the transmitter and may even be in the receiver. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
