Statistical Learning Signals for Complex Visual Images in Macaque Early Visual Cortex

Autor: Victor Vergnieux, Rufin Vogels

Publikováno v: Frontiers in Neuroscience, Vol 14 (2020)

Animals of several species, including primates, learn the statistical regularities of their environment. In particular, they learn the temporal regularities that occur in streams of visual images. Previous human neuroimaging studies reported discrepa

Visual neuroprostheses are yet limited and Simulated Prosthetic Vision (SPV) is used to evaluate potential and forthcoming functionality of these implants. SPV has been used to evaluate the minimum requirement on visual neuroprostheses characteristic

International audience; Vista space (VS) is a psychological space whose scale is “larger than the body but can be visually apprehended from a single place without appreciable locomotion” [Montello, 1993]. Moreover, VS can combine to represent lar

International audience; Clinical trials reveal that current visual neuroprosthesis are not yet usable. The main reason is the small number of implanted electrodes, leading to a very poor visual resolution. The resolution is especially not sufficient

International audience; In this study, we used a simulation of upcoming low-resolution visual neuroprostheses to evaluate the benefit of embedded computer vision techniques in a wayfinding task. We showed that augmenting the classical phosphene rende
