Figure 1.
Photomicrographs of Nissl-stained hemisections through the telencephalon, rostral to caudal as A–C, with mirror-image line drawings. The visual thalamofugal projection from the dorsal lateral geniculate nucleus to the Wulst (hyperpallium) is shown in A (the comparable somatosensory pathway to the Wulst is rostral to the level shown here). The visual tectofugal pathway via nucleus rotundus to the entopallium is shown in A and B, and the auditory tectofugal pathway via nucleus ovoidalis to field L is shown in C. Abbreviations: CM, caudal mesopallium; E, entopallium; Ep, perientopallium; H, hippocampal formation; L1, field L1 pallii; L2, field L2 pallii; L3, field L3 pallii; M, mesopallium; N, nidopallium; Nc, nidopallium caudale; W, Wulst (hyperpallium). The subpallium is indicated by shading.
