top-down feedback along the ventral visual pathway is mainly directed to foveal representations, a prediction confirmed by Reversed Depth Illusion -- happy to share this paper shorturl.at/nPdgb after >10 years of exploring a new framework (see shorturl.at/EZlNV or shorturl.at/Uaww3) for vision

How to understand multisensory encoding (e.g., MST neurons tuned to visual-vestibular), or multimodality encoding (e.g., MT cells tuned to depth from disparity and motion parallax) through the efficient coding principle, see www.sciencedirect.com/science/arti...
comments welcome!

online vision courses, free, available at zhaoping.thinkific.com , including
5 sub-courses from "Introduction to vision" to computational vision topics. They have been used for my teaching, you may mix and match them for graduate courses or self study. Comments welcome
