Reentrant signaling among simulated neuronal groups leads to coherency in their oscillatory activity

摘要: Abstract Recent experiments have revealed tightly synchronized oscillatory discharges in local assemblies of cortical neurons as well phase coherency oscillations at distant sites. These findings are consistent with the theory neuronal group selection, a population brain function that is based on properties groups neurons. A set computer simulations shows cooperative interactions within and among can generate observed phenomena. In simulations, generated through excitatory inhibitory interactions. Different general oscillate an uncorrelated fashion. Coherency activity different depends crucially reciprocal reentrant signaling reflect spatial continuity stimulus. Separated or discontinuous features given stimulus be transiently associated temporally coherent pattern between networks responding to aspects simulation arrays selective for oriented lines motion displays cross-correlations responsive parts contour if these move together. Such might used discrimination from other stationary differentially moving elements visual scene.
