Caudate nucleus
Part of the basal ganglia, it forms the striatum together with the putamen. Anatomically, the caudate nucleus is located frontally in the center of the brain and extends backward, forming a C shape. It consists of a head (caput nuclei caudati), a body (corpus nuclei caudati), and a tail (cauda nuclei caudati). In contrast to the more motor-related parts of the basal ganglia, this area is strongly connected to the prefrontal cortex in addition to its motor functions. As a result, this part of the striatum is also heavily involved in cognition, motivation, and emotion.

Cortisol
A hormone produced by the adrenal cortex that is primarily an important stress hormone. It belongs to the group of glucocorticoids and influences carbohydrate and protein metabolism in the body, suppresses the immune system, and acts directly on certain neurons in the central nervous system.

Pulvinar
The pulvinar is a fairly large nucleus in the posterior thalamus that is connected to many visual centers. It appears to increase the excitability of cells in the visual cortex as soon as a stimulus is noticed. Some studies suggest that the pulvinar may also indirectly support language processing via cortical connections.

Nonspecific Thalamus
The "non-specific" thalamic nuclei, which have only a few connections to the cortex that are not limited to a specific area, are collectively referred to as the nonspecific thalamus and sometimes truncothalamus. It receives inputs from the reticular formation, the basal ganglia, and the cerebellum. Efferences go to most of the other thalamic nuclei.
