(It is fair to say that the definite location of these capacities in definite areas has been challenged by Marie, Moutier and others, but this denial does not deny the organic brain location of speech memories; it merely affirms that they are scattered rather than concentrated in one area.)

In childhood impressibility is high, but until the age or four or five the duration of impression is low, and likewise the power of voluntary recall. In youth (eighteen-twenty) all these capacities are perhaps at their highest. As time goes on impressibility seems first of all to be lost, so that it becomes harder and harder to learn new things, to remember new faces, new names.

The typical senile defect is the dropping out of the recent memories, though the past may be preserved in its entirety. With any disease of the brain, temporary or permanent, amnesia or memory loss may and usually is present (e. g., general paresis, tumor, cerebral arteriosclerosis, etc.). As the result of Carbon monoxide poisoning, as after accidental or attempted suicidal gas inhalation, the memory, especially for the most recent events, is impaired and the patient cannot remember the events as they occur; he passes from moment to moment unconnected to the recent past, though his remote past is clear. Since memory is the basis of certainty, of the feeling of reality, these unfortunates are afflicted with an uncertainty, a sense of unreality, that is almost agonizing.
