Hue maps in primate striate cortex.
The macaque striate cortex (V1) contains neurons that respond preferentially to various hues. The properties of these hue-selective neurons have been studied extensively at the single-unit level, but it is unclear how stimulus hue is represented by the distribution of activity across neuronal populations in V1. Here we use the intrinsic optical signal to image V1 responses to spatially uniform ...
متن کاملHierarchy of Hue Maps in the Primate Visual Cortex
Many stimulus attributes are represented in the cortex in the form of a map, such as the retinotopic map in the visual cortex and the frequency map in the auditory cortex where nearby cortical locations are associated with similar values of a given stimulus or action attribute. Given the computational advantage of maps for processing information,1 it is likely that a cortical region with a mapp...
متن کاملThe V1-V2-V3 complex: quasiconformal dipole maps in primate striate and extra-striate cortex
The mapping function w = k log(z + a) is a widely accepted approximation to the topographic structure of primate V1 foveal and parafoveal regions. A better model, at the cost of an additional parameter, captures the full field topographic map in terms of the dipole map function w = k log[(z + a)/(z + b)]. However, neither model describes topographic shear since they are both explicitly complex-...

متن کاملDeoxyglucose analysis of retinotopic organization in primate striate cortex.
We have anatomically analyzed retinotopic organization using the 14C-labeled 2-deoxy-D-glucose method. The method has several advantages over conventional electrophysiological mapping techniques. In the striate cortex, the anatomical substrate for retinotopic organization is surprisingly well ordered, and there seems to be a systematic relationship between ocular dominance strips and cortical m...
