Basal Ganglia Psychology Definition

This system of tiny nuclei interconnects with other brain structures like the cerebral cortex thalamus and other regions of the brain. The basal ganglia is a group of nuclei lying deep in the subcortical white matter of the frontal lobes.

Definition of the Basil Ganglia The basal ganglia also known as basal nuclei is a region on the underside of the brain that plays a very important role in muscle coordination and movement.

Basal ganglia psychology definition

. This area works in conjunction with the midbrain to help us avoid moving in choppy fragmented ways. The basal ganglia caudate nucleus putamen globus pallidus and amygdala are involved in mediating movement higher cognitive functions attention and emotions Giedd 2008. The basal ganglia include the caudate putamen substantia nigra globus pallidus nucleus accumbens and subthalamic nucleus.

Motor control cognition emotions and learning. An area of the forebrain that is important to smooth muscle movement and actions. Its functions include organizing motor behavior and coordinating rule-based habit learning.

Basal ganglia definition The basal ganglia are a brain structure made up of a series of subcortical nuclei located at the base of the brain. The term bradyphrenia has been applied to this presumed slowing of thought in Parkinsons disease and implies 1 that increased response latencies are not strictly motoric but are due to slowed information processing and 2 that the mental slowing is analogous to the bradykinesia observed in the motor domain and hence attributable to dysfunction of dopaminergic basal ganglia mechanisms. A collection of nuclei plural of nucleus found deep within the cerebral hemispheres of the brain which includes the caudate nucleus putament.

Psychology Definition of BASAL GANGLIA. A collection of structures thought to be especially important in voluntary movement but also with important roles in cognition learning motivation and other functions. The basal ganglia or basal nuclei are clumps of gray mass located below the cortex in the depth of both cerebral hemispheres 1.

However in the brain part of the central nervous system the basal ganglia is a group of nuclei interconnected with the cerebral cortex thalamus and brainstem associated with a variety of functions. Lenroot Giedd 2006 and they have reciprocal connections with the substantia nigra in the midbrain. These nuclei can have different shapes and are involved in the control of movement.
