Vision: systems & circuits

This lecture delves into the organization of receptive fields in the primary visual cortex, discussing the orientation and position responses of neurons, the concept of 'simple' and 'complex' cells, and the mapping of orientation preferences. It explores the visual brain areas beyond V1, the evolution-driven differences in visual pathways across species, and the role of prey/predator relations in evolution. The lecture also covers the processing pathways of visual information, the neural mechanisms underlying escape behavior, and the encoding and decoding models for vision using neural networks.
