title: [Early ontogenetic development of regular organization of corticocortical connections between visual areas 17 and posteromedial lateral suprasylvian area in the cat].
abstract: Early ontogenetic development of cluster organization of corticocortical connections between visual areas 17 and posteromedial lateral suprasylvian area (PMLS) was studied in cat. Retrograde axonal tracer horseradish peroxidase was microinjected into the area PMLS. Labeled initial neuron distribution was analyzed in area 17 in 5- and 12-week-old kittens. A significant increase of the cortical surface area containing labeled neurons together with the decrease in their distribution density were shown between weeks 5 and 12. An analysis of amplitude and phase of Fourier spectra of labeled neuron distribution patterns demonstrated some differences between the kittens of various age groups and indicated the incompleteness of connection cluster organization formation. The temporal morpho-functional features of the development of PMLS zone corticocortical connections, as compared to the other visual cortical areas, are discussed.
