MDmc lesions. Schematic diagrams of six sections, 1 mm apart, through the posterior thalamus of a monkey taken from Gaffan and Murray (1990). The next three columns show photomicrographs of the MDmc lesions for MD1–MD3 corresponding as closely as possible to the each of the schematic diagrams. (Photomicrographs of MD4 and MD5 are shown in Figure 2.) Arrowheads indicate the site of each lesion.
