Seventy-nine patients with unilateral frontal- or temporal-lobe excisions and 18 normal control subjects were tested on four self-ordered tasks requiring the organization of a sequence of pointing responses. There were two verbal and two nonverbal tasks. Patients wih excisions from the left frontal lobe exhibited significant impairments on all four tasks,(More)
We used positron emission tomography to investigate word generation in subjects whose first language was English but who were also proficient in French. These subjects performed three types of lexical search: rhyme generation based on phonological cues, synonym generation requiring a semantic search, and translation involving access to a semantic(More)
-The report attempts to delineatecertain residual learning capacities of H.M., a young man who became amnesic in 1953 following a bilateral removal in the hippocampal zone. In addition to being able to acquire new motor skills (CoRKIN [2]), this patient shows some evidence of perceptual learning. He also achieves some retention of very simple visual and(More)
Regional cerebral blood flow was measured with positron-emission tomography during two encoding and two retrieval tasks that were designed to compare memory for object features with memory for object locations. Bilateral increases in regional cerebral blood flow were observed in both anterior and posterior regions of inferior temporal cortex and in ventral(More)
The recall of spatial location in patients with left or right temporal-lobe lesions was studied in two experiments, in which recall was tested either immediately after presentation of an array of objects, or after an intervening verbal task, a spatial task or an unfilled interval. Deficits were found only in patients with right temporal-lobe lesions that(More)
Three recency-discrimination tasks (involving concrete words, representational drawings and abstract paintings) were administered to 117 patients who had undergone unilateral cortical removals, and to 20 normal control subjects. Frontal or anterior temporal-lobe excision did not impair simple item recognition, and neither left nor right anterior-temporal(More)
The neural representation of the languages of the polyglot speaker has been highly controversial. We used positron emission tomography (PET) to investigate whether production in a second language (L2) involves the same neural substrates as that of a first language (L1) in normal bilingual subjects who learned L2 after the age of 5 years. Comparison of(More)
