MACAQUE’S PRIMARY VISUAL CORTEX WAHIBA TAOUALI, GIACOMO BENVENUTI, FRÉDÉRIC CHAVANE, AND LAURENT U. PERRINET Institut de Neurosciences de la Timone UMR7289, CNRS & Aix-Marseille Université 1. MOTIVATION 1. When an oriented moving bar reaches the classical receptive field (cRF) of V1 neurons, how are directional and orientational (tuning) information dynamically encoded in their activity? 2. How could this information be decoded from a V1 population, within and outside the cRF (while approaching or passing the RF) ?

A dynamic model for decoding direction and orientation in macaque primary visual cortex.
Using observations of spiking activity in a population of neurons from macaque primary visual area, we studied simultaneously the dynamics of direction and orientation decoding. Stimuli consisted of oriented bars moving in 12 different directions, the orientation being orthogonal to the direction. Bars move from 3 degrees before to 1.5 degrees after the receptive field center (RFc). We first fi...

متن کاملA possible low-level explanation of "temporal dynamics of brightness induction and White's illusion"
Based upon physiological observation on time dependent orientation selectivity in the cells of macaque’s primary visual cortex together with the psychophysical studies on the tuning of orientation detectors in human vision we suggest that time dependence in brightness perception can be accommodated through the time evolution of cortical contribution to the orientation tuning of the ODoG filter ...
متن کاملThe basis of orientation decoding in human primary visual cortex: fine- or coarse-scale biases?
Orientation signals in human primary visual cortex (V1) can be reliably decoded from the multivariate pattern of activity as measured with functional magnetic resonance imaging (fMRI). The precise underlying source of these decoded signals (whether by orientation biases at a fine or coarse scale in cortex) remains a matter of some controversy, however. Freeman and colleagues (J Neurosci 33: 196...
متن کاملA Multi-Stage Model for Fundamental Functional Properties in Primary Visual Cortex
Many neurons in mammalian primary visual cortex have properties such as sharp tuning for contour orientation, strong selectivity for motion direction, and insensitivity to stimulus polarity, that are not shared with their sub-cortical counterparts. Successful models have been developed for a number of these properties but in one case, direction selectivity, there is no consensus about underlyin...
