  • Title: [Spatial distribution of heterogeneous afferent influences in the visual cortex of the guinea pig].
    Author: Chebkasov SA.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1982; 32(6):1156-63. PubMed ID: 7164581.
    Abstract:
    In the 17-th area of guinea pig's visual cortex the electric stimulation of LGN, SC, and the cortex itself creates within the zones of the column-like ensembles of neurones excited by the light flash, local excited groups, with overlapping marginal zones. Together with analogous results of the MBRF stimulation this demonstrates that different functional neuronal ensembles achieve various forms of functioning of the same structural units of the cortex structure, i.e. columns. Thus, convergence of specific, unspecific and cortico-cortical afferent influences upon individual columns take place. This phenomenon suggests a realization of a higher, as compared with cellular, level of the nervous integration by neuronal ensembles.
