Caudate nucleus

The nucleus caudatus (from Latin nucleus "core" and cauda "tail", "tail") is a pair of large nucleus in the telencephalon (endbrain). It is part of the basal ganglia and is therefore responsible for controlling voluntary movements. In addition, this structure appears to be one of several involved in assessing the trust of subjects and objects.

The caudate nucleus lies in the depths of the cerebral hemispheres, directly on the wall of the first or second cerebral ventricle, and partially bulges into it. It has a C-shaped appearance with a wider, forward head ( Caput nuclei caudati ), a body ( Corpus nuclei caudati ) and a tail ( Cauda nuclei caudati ).

The caudate nucleus is separated from the putamen lying to the side by a strip of white matter (i.e. nerve fibers ), the internal capsule . Putamen and caudate nucleus are also grouped together as the striatum .

The corpus striatum ("striped body") is usually used synonymously with the short form striatum, which is preferred in the specialist literature. However, some representations close the Ncl. caudatus, the putamen and the globus pallidus (pallidum).

The Spanish physiologist José Manuel Rodriguez Delgado gained attention by implanting a probe into a bull that could remotely deliver electrical impulses directly to the caudate nucleus. Delgado used this in an arena to apply a stimulation every time the bull came towards him, which stopped the bull's attack. At first Delgado believed he had found a way to inhibit aggressiveness.
