  2. Basal ganglia - Wikipedia

    en.wikipedia.org/wiki/Basal_ganglia

    Video of relevant anatomy Coronal slices of human brain showing the basal ganglia. White matter is shown in dark gray, gray matter is shown in light gray. Anterior: striatum, globus pallidus (GPe and GPi) Posterior: subthalamic nucleus (STN), substantia nigra (SN) The basal ganglia form a fundamental component of the cerebrum.

  3. Subthalamic nucleus - Wikipedia

    en.wikipedia.org/wiki/Subthalamic_nucleus

    The subthalamic nucleus (STN) is a small lens-shaped nucleus in the brain where it is, from a functional point of view, part of the basal ganglia system. In terms of anatomy, it is the major part of the subthalamus. As suggested by its name, the subthalamic nucleus is located ventral to the thalamus.

    en.wikipedia.org/wiki/Nucleus_accumbens

    Location: The shell is the outer region of the nucleus accumbens, and – unlike the core – is considered to be part of the extended amygdala, located at its rostral pole. Cell types: Neurons in the nucleus accumbens are mostly medium spiny neurons (MSNs) containing mainly D1-type (i.e., DRD1 and DRD5 ) or D2-type (i.e., DRD2 , DRD3 , and ...

  6. Globus pallidus - Wikipedia

    en.wikipedia.org/wiki/Globus_pallidus

    The globus pallidus is a structure in the brain involved in the regulation of voluntary movement. [8] It is part of the basal ganglia, which, among many other functions, regulate movements that occur on the subconscious level. The globus pallidus has a predominantly inhibitory effect on movement regulation, balancing cerebellar excitation.

  7. Striatum - Wikipedia

    en.wikipedia.org/wiki/Striatum

    The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.

  8. Putamen - Wikipedia

    en.wikipedia.org/wiki/Putamen

    The basal ganglia are located bilaterally, and have rostral and caudal divisions. The putamen is located in the rostral division as part of the striatum. The basal ganglia receive input from the cerebral cortex, via the striatum. This is a transverse section of the striatum from a structural MR image.
