✦ Synopsis

Microelectrode penetrations normal to the layers of foveal striate cortex in awake, behaving monkeys have revealed two new facts about the distribution of orientation preferences in this tissue: (1) In the top layers there is a predominance of vertical orientation preferences at eccentricities of less than 30 min, and a predominance of oblique orientation preferences at eccentricities of 30 min to 2 deg. (2) At all eccentricities between 0 and 2 deg there is a striking difference in orientation preference between upper layer (supragranular) and lower layer (infragranular) cells.
