_Other Neurotic Symptoms_.--Janet's studies at the Salpetriere seem to show that the alterations of memory which bring about what we call {150} secondary personality (the forgetting of certain phases of existence and the maintenance for a time of a small portion of consciousness and memory quite apart from the rest) correspond with alterations in the physical basis of memory, that is, in the circulation to certain portions of the brain, and probably also in the modes of association of brain cells. They occur, particularly, in connection with certain phenomena of hystero-epilepsy so-called, or with the deeper forms of epilepsy in which there are various paresthesias, hyperesthesias and anesthesias as a consequence of a disturbance of the circulation in the central nervous system; and probably also of the connections made by neurons and the movements of neuroglia cells in making and breaking these connections. These alterations of memory are represented physically by such cases as those in which patients so lose their consciousness of sensation that they are unable to tell even where their feet are. As they themselves say, "they have lost their legs." In these cases, patients are often very deaf or have a limited auditory power, and their fields of vision are extremely narrowed. In most of these cases, recovery of the original personality takes place after hypnosis. This probably represents a relaxation of that short-circuiting, within the nervous system, which brought about the curious phenomenon studied as secondary personality.
