Dear Notetaker:
... o In the retina and LGN there are neurons that are classified as M-like, P-like, or K-like with different anatomical features and functions o In V1 the info from P, K, and M cells is recombined, it does not stay segregated o The recombined info is sent to extra striate areas for even more processing ...
