Laminar segregation of color cells in the monkey's striate cortex.
In the monkey's striate cortex concentric cells with double opponent color properties were restricted to layers 4A and 4C beta; this cell type was also found in the lower half of 4C alpha but there it was always of the broad band class. Concentric cells of any type were absent from 4B. Simple cells were found in abundance in 4B and upper 4C alpha and were always broad band while those few found in 4A and 4C beta were usually double opponent color but sometimes were broad band. Color-sensitive complex and hypercomplex cells were found in the supragranular and infragranular layers (2, 3, 5 and 6). Double opponent concentric cells were occasionally seen in the supragranular layers but never in the infragranular laminae.
