  • Title: [Component analysis of the reactions of neuronal populations in the human brain during the memorizing of visual stimuli].
    Author: Kropotov IuD.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1984 Jul; 70(7):904-11. PubMed ID: 6489566.
    Abstract:
    The components of the evoked impulse activity of neurons and neuronal populations were studied in different nuclei of the thalamus and strio-pallidar system of the human brain, in patients treated with indwelled electrodes. The impulse activity was recorded during recognition of polygonal shapes with and without semantic meaning, during memorizing of visual stimuli without meaning. Peri-stimulus-time histograms for the cases of presentations of familiar and unfamiliar patterns, for the cases of stimulus presentation in the initial and terminal parts of the memorizing were computed and compared with each other. In some neuronal populations, a group of late components was revealed, altering during learning and depending upon subject evaluation of the meaning of the stimulus.
