Journal ArticleDOI
Visuotopic organization and extent of V3 and V4 of the macaque
TL;DR: In both V3 and V4, the representation of the central visual field is magnified relative to that of the periphery; however, at a given eccentricity, the receptive fields of V4 are larger than those of V3.
Journal ArticleDOI
Visual Topography of V2 in the Macaque
TL;DR: The representation of the visual field in the area adjacent to striate cortex was mapped with multi unit electrodes in the macaque using multiunit electrodes in each animal over several recording sessions.
Journal ArticleDOI
Topographical organization of cortical afferents to extrastriate visual area PO in the macaque: a dual tracer study.
TL;DR: The origin and topography of cortical projections to area PO, an extrastriate visual area located in the parieto‐occipital sulcus of the macaque, is examined.
Journal ArticleDOI
Visual topography of striate projection zone (MT) in posterior superior temporal sulcus of the macaque.
Ricardo Gattass,Charles G. Gross +1 more
TL;DR: The results further support the suggestion that MT in the macaque is homologous to visual area MT in New World primates and is similar to striate cortex in being a first-order transformation of the visual field.
Journal ArticleDOI
Cortical Connections of Area V4 in the Macaque
TL;DR: The results indicated that all parts of V4 are connected with occipital areas V2, V3, and V3A, and the predominance of central field projections from V4 to inferior temporal areas isistent with the needfordetailed analysis for object vision.
