Abstract
A battery of tests clinically employed for the estimation of auditory and visual recent memory dysfunction was administered to 8 human subjects having circumscribed damage to the temporal lobe. It was hypothesized that the performance of subjects with temporal lobe lesions would qualitatively resemble that of subjects intoxicated with marihuana. Where comparisons could be made, the performance of these temporal lobe patients paralleled the performance of subjects acutely intoxicated with known doses of .DELTA.9-THC [.DELTA.9-tetrahydrocannabinol]. Cannabinoid actions on hippocampal functioning are discussed. The hypothesis that the action of marihuana in the brain may focus in the hippocampal region and produce behavioral changes similar to that resulting from traumatic injury or removal of the region is supported.
