A putative striato-dorsal thalamic pathway in lizards

Brain Research Bulletin

Abstract

Striatal targets related to the dorsal thalamus were studied in reptiles. The lateral striatum projects to globus pallidus and to three cellular groups associated to the lateral forebrain bundle: the anterior entopeduncular nucleus, the suprapeduncular nucleus, and the ventromedial thalamic nucleus. The projection is heavier on the suprapeduncular nucleus, which in turn projects on nucleus rotundus in the dorsal thalamus. Nucleus rotundus is the origin of a prominent projection to the lateral striatum among other forebrain areas. The intermediomedial striatum projects also to globus pallidus and to the three cellular groups associated with the lateral forebrain bundle, but in this case, the projection is heavier on the ventromedial thalamic nucleus. The latter nucleus targets a number of nuclear aggregates in the ventral tier of the dorsal thalamus, which in turn project to the intermediomedial striatum. As in mammals, the striatum in reptiles may influence through these pathways its input from the dorsal thalamus.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
