Here we synthesize this recent evidence and propose that the ventral pathway is best understood as a recurrent occipitotemporal network containing neural representations of object quality both utilized and constrained by at least six distinct cortical and subcortical systems.

Jan 15, 2010 · Using fMRI, we delineated dorsal and ventral human retinotopic areas V1, V2, and V3, as well as a quarter-field visual field representation lateral to V3v, V4 (v), in 24 healthy subjects. Based on these individual definitions, a functional maximum probability map (fMPM) was then computed in analogy to the aMPM.

Jan 15, 2010 · Retinotopic areas V1, V2, V3v, V3d, and V4(v) were delineated in the functional datasets using the standard phase mapping techniques which probe for each voxels' optimal stimulus condition with respect to polar angle (Sereno …

Nov 16, 2022 · How variable is the functionally defined structure of early visual areas in human cortex and how much variability is shared between twins? Here we quantify individual differences in the best understood functionally defined regions of cortex: V1, V2, V3.

We used cytoarchitectonically-defined probability maps for the early extrastriate cortex, consisting of areas corresponding to V2, V3d, V3v/VP, V3a, and V4v. Gray matter volumes were compared between groups, supplemented by testing associations with clinical symptoms.

Jan 1, 2001 · Our results provide architectonic and connectional evidence for the existence of retinotopically organized dorsal and ventral halves of V3 (V3d and V3v, respectively) along the outer border of the dorsal and ventral halves of V2, and the DM visual area rostral to the dorsal portion of V2 near the medial wall but displaced from the V2 border by ...

Sep 1, 2009 · We found target sites of these transcallosal fibers at borders of cytoarchitectonically defined occipital areas not only between early visual areas V1 and V2, V3d and V3A, and V3v and V4, but...

Jan 15, 2010 · This question is addressed here directly by correlating architectonic and functional delineations of the early visual areas V1, V2, V3d, V3v, and V4(v).

Jan 15, 2010 · Visual perception of three-dimensional (3D) structure is important for object recognition, grasping, and manipulation. The 3D structure of a surface can be defined in terms of its slant and tilt.…

V2 / V3 / VP = extrastriate visual areas. Preliminary visual processing, properties become more complex and receptive fields become larger at higher levels; Each has a dorsal part (V1d, V2d and V3d, above calcarine representing lower visual field) and a ventral part (V1v, V2v, VP=V3v, below calcarine representing upper visual field)
