Jul 24, 2023 · It has a multitude of functions associated with reward and cognition but is primarily involved in motor control. In particular, the basal ganglia is considered to be a gate-keeping mechanism for the initiation of motor movement, effectively choosing which actions to allow and which actions to inhibit.
Basal ganglia, group of nuclei (clusters of neurons) in the brain that are located deep beneath the cerebral cortex (the highly convoluted outer layer of the brain). The basal ganglia specialize in processing information on movement and in fine-tuning the activity of brain circuits that determine

Jun 30, 2020 · Although widely used, the term basal ganglia is a misnomer, as ganglia are collection of cell bodies outside of the central nervous system. Since a collection of subcortical cell bodies inside the nervous system are known as nuclei, the name b asal nuclei is more accurate.

The “basal ganglia” refers to a group of subcortical nuclei responsible primarily for motor control, as well as other roles such as motor learning, executive functions and behaviors, and emotions.

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).

Oct 30, 2023 · Along with the initial signal to the striatum, the cerebral cortex suppresses competing motor programs by the indirect and hyperdirect pathways. When excited by the glutamatergic inputs of the cerebral cortex, striatum sends inhibitory signals to the GPe which normally exerts GABAergic inhibition on the STN.
