Distribution of monoamine-containing terminals and fibers in the central nervous system of the chicken.
In the mesencephalon of the chicken, the two large groups of CA terminals and fibers appeared to correspond to the dorsal and ventral bundles of the CA containing fibers in the rat. These ran rostrally in the medial forebrain bundle and appeared to terminate within the thalamus, hypothalamus, preoptic region and corpus striatum. 5-HT containing terminals and fibers also were observed in the mesencephalon and appeared to run rostrally in the medial part of the medial forebrain bundle. In comparison with the CA terminals, however, 5-HT terminals were for the greater part, difficult to observe in many areas of the brain. Based on the observation concerning postnatal ontogeny of monoamine-containing neurons, the chicken brain appears to acquire behavioral and functional maturity at an earlier stage after birth than does that of the rat. Effect of reserpine, nialnmide, L-Dopa and 5-HTP on the monoamine-containing terminals and fibers are briefly discussed.
