We report a patient with phonological agraphia (selective impairment of kana [Japanese phonetic writing] nonwords) and acalculia (mental arithmetic difficulties) with impaired verbal short-term memory after a cerebral hemorrhage in the opercular part of the left precentral gyrus (Brodmann area 6) and the adjacent postcentral gyrus. The patient showed phonemic paragraphia in five-character kana nonword writing, minimal acalculia, and reduced digit and letter span. Mental arithmetic normalized after 8 months and agraphia recovered to the normal range at 1 year after onset, in parallel with an improvement of the auditory letter span score from 4 to 6 over a period of 14 months and in the digit span score from 6 to 7 over 24 months. These results suggest a close relationship between the recovery of agraphia and acalculia and the improvement of verbal short-term memory. The present case also suggests that the opercular part of the precentral gyrus constitutes the phonological route in writing that conveys phonological information of syllable sequences, and its damage causes phonological agraphia and acalculia with reduced verbal short-term memory.

Two aspects of memory defects following circumscribed neocortical lesion are considered. First, the selective impairment involving one category of stimuli (e.g. faces, colours) or a specific mnestic ability (spatial orientation). The deficit affects ‘new’ as well as ‘old’ memories and suggests that engrams are located in discrete cortical areas. The second issue concerns the relation of the hemispheric side of lesion to memory of non-verbal visual material, as a function of the differential utilization of the visual and verbal code in carrying out the task. Short-term memory tests are performed poorly by aphasics. In long-term memory tests, the performance depends on the nature of the task: in the early stages of paired-associate learning aphasics are impaired, on recurring figure recognition no hemispheric difference emerges, on sequential memory right brain-damaged patients have the poorest scores.

A specific component of human memory, the phonological short-term memory, plays a substantial role in the acquisition of new words. Both the short-term store and the rehearsal components of the system appear to be involved.

Short-term memory for nonwords, like real words, may be supported both by long-term knowledge about the sound structures of familiar words in the language and the phonological loop component of working memory. It cannot therefore be safely assumed that employing nonwords in memory experiments will guarantee dependence only on the phonological loop.
