The purpose of this selective review is to present and to discuss some of the considerable information that has been obtained from the neuropathological examination of the human brain in cases of amnesia. This evidence has led to the conclusion that the retention and perhaps, to some extent, the recall of sensory impressions and experience are dependent upon the structural integrity of certain small and relatively well-defined regions of the brain. This conclusion does not imply that the functions of retention and recall are carried out within these regions, any more than that the unconsciousness resulting from a small lesion in the upper brainstem justifies the conclusion that consciousness resides at this level.The ability to receive a sensory impression, to retain it and to recall it at the appropriate moment, will be referred to as the process of memorizing. Some disturbance of this process is a salient feature of many of the disorders of memory that have an organic basis, and those that occur in hysteria and the functional psychoses will not be considered here. In clinical practice, four terms are commonly used to describe disorders of memorizing. The first is a defect of'immediate memory'and is usually evinced by a reduced digit-retention span. The second term is a defect of'recent'or'short-term memory'or of'memory for recent events'. Here the reduced retention span is one of hours or even days. A distinction between these two terms is not always made and Brown (1964), in a review of ‘short-term memory', uses this latter term to describe retention for a period of seconds or minutes. It may be that the distinction between'immediate'and'recent memory'is more artificial than real, and due to the fact that the presentation of digits lends itself to easy quantitative assessment of retention. The retention
