[Distrubance in retention of a conditioned feeding behavior in mice by subconvulsant electrical stimulation of the cerebral cortex].
A bilateral 80 s stimulation of the parieto-occipital cortex was applied 200 s after a former partial acquisition test in a Skinner box. It has resulted in an impairment of the performances obtained 24 h later through a second test. This effect was greater the greater the stimulus, this latter being always kept under threshold values of post-discharges. These results seem to reveal that reminiscence phenomena are under the control of neocortex, in a somewhat discrete way which does not produce any retrograde amnesia.
