Choline acetyltransferase-like immunoreactivity in the forebrain of the red-eared pond turtle (Pseudemys scripta elegans)
Choline acetyltransferase (ChAT) immunohistochemistry was used to map the cholinergic neurons in the forebrain of Pseudemys turtles. Cell bodies with ChAT-like immunoreactivity were seen in the septum, the nucleus of the diagonal band, and embedded within the medial and lateral forebrain bundles. The region of the medial and lateral forebrain bundles contained the greatest concentration of ChAT-positive neurons. Virtually no ChAT-like immunoreactivity was seen in the areas composing the reptilian homologue of the mammalian striatum. It is suggested that the turtle basal forebrain cholinergic neurons may represent the evolutionary precursors to the mammalian cholinergic neurons of the basal forebrain and even the striatum. © 1984.
