A corticotectal projection in the lizard Agama agama.
Following lesions in the dorsal cerebral cortex of the lizard Agama agama, terminal degeneration was observed by the Fink-Heimer technique in the mediodorsal cortex, septal area, nucleus periventricularis and area lateralis of the hypothalamus after 7 days survival time. Following longer survival times (up to 28 days) diffuse terminal degeneration was found in layers 7 to 13 laterally and medially in the optic tectum. Terminal degeneration of the electron-dense type was found in electron micrographs of the same areas of the optic tectum.
