  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. 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.

  4. 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.

  5. 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.

  6. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    The basal ganglia, also called basal nuclei, are a set of structures deep within the hemispheres involved in behaviour and movement regulation. [28] The largest component is the striatum , others are the globus pallidus , the substantia nigra and the subthalamic nucleus . [ 28 ]

  7. Limbic system - Wikipedia

    en.wikipedia.org/wiki/Limbic_system

    The limbic system also interacts with the basal ganglia. The basal ganglia are a set of subcortical structures that direct intentional movements. The basal ganglia are located near the thalamus and hypothalamus. They receive input from the cerebral cortex, which sends outputs to the motor centers in the brain stem. A part 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. 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 .
