Visual information processing of the brain

2nd-October-2020

Structure of the visual cortex (ventral cortical visual pathway) - propagation with feed forward - hierarchy: simple feature extraction - to complex things - processing in the IT field: "grandmother cell" hypothesis and "population code" hypothesis

How is general object recognition done in the brain?

• Present images to monkeys; Measure activity patterns of brain V1, V2, V4, IT field • Classify "code" derived from measurement field of IT field by SVM Then you can achieve the same recognition performance as a person - can not do with "code" up to the V4 field
