Basal nucleus
A collection of nerve cells in the basal region of the telencephalon. The basal ganglia are considered to be an important producer of the neurotransmitter acetylcholine. In Alzheimer's patients and, in some cases, Parkinson's patients, the basal ganglia degenerate. As a result, they produce less and less acetylcholine, which neurologists associate with some of the symptoms of these diseases.

Striatum
The striatum is a central structure of the basal ganglia. It consists of the caudate nucleus and putamen; the nucleus accumbens is also functionally part of it as its ventral portion. As the most important input structure of the basal ganglia, the striatum plays an essential role in controlling movement sequences as well as in cognition, motivational processes, and the reward system.

Pallidum
The "pale nucleus" (pallidum = pale) is classified as part of the basal ganglia due to its functional integration and, in terms of evolutionary development, belongs to the telencephalon. It has an inner (medial) and an outer (lateral) segment, which mainly transmit inhibitory impulses to modulate the activity of other parts of the basal ganglia and thalamus.

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.

Pallidum
The globus pallidus, also known as the pallidum, is an important nucleus of the basal ganglia. It is a motor nucleus of the extrapyramidal system involved in the regulation of movement. The pallidum has an inhibitory and an excitatory part. The Latin name pallidus – pale – refers to the color of this nucleus.

Nucleus accumbens
The nucleus accumbens is a nucleus in the basal ganglia that receives dopaminergic (dopamine-responsive) inputs from the ventral tegmental area. It is associated with reward and attention, but also with addiction. In pain processing, it is involved in motivational aspects of pain (reward, pain reduction) and in the effect of placebos.

Putamen
A nucleus of the basal ganglia that, together with the caudate nucleus, forms the striatum. As part of the extrapyramidal motor system, it is involved in voluntary motor function (intentional movement).
