This would also seem to implicate the basal ganglia in on-line control.
They base their hypothesis on clinical evidence that basal ganglia dysfunction allows slow idling cortical rhythms to predominate.
However, due to lack of specific investigation of basal ganglia in catatonia, both assumptions remain speculative.
Intense staining was also detected in the cells of the ventral and dorsal ganglia located between the nerve ring and the pharyngeal gland cells.
In the intact ganglia, satellite cells are tightly apposed to neurons and have a distinct morphology that permits clear identification.
Thus, basal ganglia receive a major input from the dorsal thalamus, as in amphibians.
There are indications that separate operations in procedural learning are affected by damage to the frontal lobes, basal ganglia, and cerebellum.
This has been suggested to result in disruption of the basal ganglia-thalamocortical circuits leading to obsessive-compulsive symptoms.
