MDmc lesions. Schematic diagrams of six sections, 1 mm apart, through the posterior medial thalamus of a monkey taken from Gaffan and Murray (1990). The next three columns show photomicrographs of the MDmc lesions for MD1, MD2, and MD3 corresponding as closely as possible to the each of the schematic diagrams. Arrowheads indicate the site of each lesion. AD, Anterodorsal nucleus; AM, anteromedial nucleus; AV, anteroventral nucleus; Ca, caudate nucleus; CeM, central medial nucleus; CL, central lateral nucleus; CM, center median nucleus; CSL, central superior lateral nucleus; FX, fornix; Hl, lateral habenular nucleus; Hm, medial habenular nucleus; Hpt, habenulopeduncular tract; IT, inferotemporal cortex; LD, lateral dorsal nucleus; Li, limitans nucleus; LP, lateral posterior nucleus; MD, mediodorsal nucleus; MDdc, mediodorsal nucleus, densocellular portion; MDmc, magnocellular portion; MDmf, mediodorsal nucleus, multiformis portion; MDpc, mediodorsal nucleus, parvocellular portion; MG, medial geniculate complex; Mm, mamillary complex; Mtt, mamillothalamic tract; Pa, paraventricular nucleus; Pc, paracentral nucleus; Pf, parafascicular nucleus; Pla, anterior pulvinar nucleus; Pli, inferior pulvinar nucleus; Pl, lateral pulvinar nucleus; Po, posterior nucleus; Pa, parataenial nucleus; R, reticular nucleus; Re, reuniens nucleus; Rh, rhomboid nucleus; SG, suprageniculate nucleus; SN, substantia nigra; St, stria terminalis; Sub, subthalamic nucleus; VA, ventral anterior nucleus; VLa, ventral lateral nucleus, anterior portion; VLp, ventral lateral nucleus, posterior portion; VMb, ventral medial nucleus, basal portion; VMp, ventral medial nucleus, principal portion; VPi, ventral posterior inferior nucleus; VPl, ventral posterior lateral nucleus; VPm, ventral posterior medial nucleus; Zi, zona incerta.
