Efferent connections of the septal area in a lizard (tupinambis nigropunctatus).
Electrolytic lesions were placed in the septal area of the lizard Tupinambis nigropunctatus, and the subsequent anterograde degeneration was studied by the use of reduced silver techniques. Telencephalic projections were found to the dorsal cortex and the nucleus of the anterior commissure. Descending fibers appeared to terminate in the preoptic area, dorsolateral and dorsomedial thalamic nuclei, medial thalamic nucleus, nucleus periventricularis hypothalami, lateral hypothalamic area, mamillary body and mesencephalic central grey. All of these connections were found to be ipsilateral.
