Rows sequentially list the M1/PM functional zones, case number of each monkey, tracer injected, and total numbers of labeled cells excluding cells labeled in the local cortical area of the injection. Cortical fields are listed in the first column, and the successive columns contain the respective percentage of labeled cells. Cells labeled in the local injection location are listed as “Inj,” and concentrations <0.1% are listed as “—.”
