Popis: Retrograde changes in the dorsal lateral geniculate body were studied following cortical radiation lesios. The cytoarchitectonic structure of the striate region is described. The peristriate as well as the striate areas are shown to receive projections form the dorsal lateral geniculate body. Thus — as far as this set of connections is concerned — the peristriate are is a subdivision of the striate region. It is further shown that the striate region as defined cytoarchitectonically is —to the extent that it was validated — coextensive with the cortical projection area of the dorsal lateral geniculate body. The dorsal lateral geniculate body is divided into an alpha and a beta sector. Evidence indicates that each vertical column of cells in the striate region receives projections from an appropriate geniculate column which extends throughout the thickness of the alpha sector. The alpha cell columns project upon the striate region in an orderly manner. Details of this organization are described. The cells of the beta sector also project upon the striate region. Whether the pattern of this projection is similar to that of the alpha sector or is more generalized has not been established. Some electrophysiological and experimental-anatomical evidence relevant to the findings is discussed.
