Adaptive weighting of binocular correlation and matching computation in stereopsis

点击翻译按钮获取中文摘要

Stereoscopic system weights correlation- and match-based disparity representations to support perception of binocular depth. We found that fine depth perception mainly uses the match-based representation, while coarse depth perception combines both. The brain also exploits correlation-based representation for rapidly refreshed stimuli, whereas match-based representation is used for slowly changing or stationary stimuli. Single-unit recording and micro-stimulation experiments in macaque monkeys show that neuronal activity in visual area V4 directly underlie fine depth judgement.We also developed techniques to apply 2-photon laser imaging to visual area V4 in monkeys, which will allow us to reveal the functional architecture of this area for stereopsis.
