  2. Basal ganglia - Wikipedia

    en.wikipedia.org/wiki/Basal_ganglia

    The basal ganglia (BG) or basal nuclei are a group of subcortical nuclei found in the brains of vertebrates. In humans and other primates , differences exist, primarily in the division of the globus pallidus into external and internal regions, and in the division of the striatum .

  3. 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.

  4. Cerebrum - Wikipedia

    en.wikipedia.org/wiki/Cerebrum

    The cerebrum (pl.: cerebra), telencephalon or endbrain [1] is the largest part of the brain, containing the cerebral cortex (of the two cerebral hemispheres) as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system.

  5. Pallidothalamic tracts - Wikipedia

    en.wikipedia.org/wiki/Pallidothalamic_tracts

    The pallidothalamic tracts (or pallidothalamic connections) [1] are a part of the basal ganglia. They provide connectivity between the internal globus pallidus (GPi) and the thalamus , primarily the ventral anterior nucleus and the ventral lateral nucleus .

  6. 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.

  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. Lentiform nucleus - Wikipedia

    en.wikipedia.org/wiki/Lentiform_nucleus

    In a coronal section through the middle of the lentiform nucleus, two medullary laminae are seen dividing it into three parts. The lateral and largest part is of a reddish color, and is known as the putamen, while the medial and intermediate are of a yellowish tint, and together constitute the globus pallidus; all three are marked by fine radiating white fibers, which are most distinct in the ...

  9. Direct pathway - Wikipedia

    en.wikipedia.org/wiki/Direct_pathway

    It also involves another basal ganglia component the substantia nigra, a part of the midbrain. [2] In a resting individual, a specific region of the globus pallidus, the internal globus pallidus (GPi), and a part of the substantia nigra, the pars reticulata (SNpr), send spontaneous inhibitory signals to the ventral lateral nucleus (VL) of the ...
