Figure 2. Schematic reconstructions show 100-electrode array placement in S1 of two owl monkey cases.

Figure 2

A. A schematic of the owl monkey brain is shown with area 3b highlighted, as neurons in areas 3a and 1 tend not to respond well to light tactile stimulation under the anesthetic conditions of these experiments. The orientation of the brain is indicated by the arrows, with R = rostral and M = medial. B–C. Electrode locations in each owl monkey case were approximated based on examination of myelin-stained sections of flattened cortex and the results of receptive field mapping during recording experiments to estimate the digit and palm pad representations. The placements of the 100-electrode array in each case tended to cover a large part of the area 3b hand representation. The 1mm scale bar refers to the array size for both monkey cases.
