Aug 5, 2022 · The basal ganglia are a group of brain structures that control movement, decision-making, reward and addiction. They are located near the center of your brain and include several nuclei and ganglia.

In the illustration to the right, two coronal sections of the human brain show the location of the basal ganglia components. Of note, and not seen in this section, the subthalamic nucleus and substantia nigra lie farther back ( posteriorly ) in the brain than the striatum and pallidum.
The basal ganglia are a group of nuclei deep beneath the cerebral cortex that process information on movement and action selection. They receive input from the cortex and thalamus, and send output to the thalamus and cortex via the basal ganglia loops.
Jul 24, 2023 · These nuclei are situated in the midbrain lying dorsal to the cerebral peduncles. The substantia nigra derives its name from its dark, neuromelanin pigment formed along the same biosynthetic pathway as dopamine.

Jun 30, 2020 · The basal ganglia are a group of subcortical nuclei that modulate and refine cortical activity, especially motor and cognitive functions. They are spread throughout the forebrain and receive inputs from the cerebral cortex and limbic system, and project to the thalamus and cortex.
Aug 3, 2023 · The basal ganglia are a subcortical cluster of interconnected cell bodies, which interact with each other through circuits that mainly modulate motricity ( Parent, 2012 ), but are also involved in coordination of behavioral and emotional functions ( Lanciego et al., 2012 ).
