Cortical projections of the medial visual area in the owl monkey, Aotus trivirgatus.

The cortical projections of the Medial Area (M) of the owl monkey were studied using the autoradiographic method. Area M projects to several extrastriate areas, including Area 18, in a pattern of terminations unlike that which would be expected if M was part of a larger Area 19 or V III band. The pattern of terminal lamination was found to be somewhat unusual in that projections were to layers VI, I and the deep portion of layer V in the major target areas.
