several large clusters of nerve cells deep in the brain below the cerebral hemispheres; crucial in coordinating motor commands. Include the striatum and the substantia nigra.
The basal ganglia are a group of structures deep within the brain involved in voluntary movement, eye movement, and cognition. For a picture and further discussion, see WWAMI Medical Education Program. close window
Are a group of functionally related nuclei, located bilaterally in the interior of the inferior aspect of the cerebrum, the midbrain and the diencephalon. They are the largest nuclei of the brain and play an important role in planning and coordinating motor movements and posture. - Exert their influence over networks that link the motor cortex to other cortical areas. They behave as a variable filter ensurring smooth muscle movements.
The part of the brain that coordinates movement.
A group of nuclei lying deep in the subcortical white matter of the frontal lobes that organize motor behavior
Masses of grey matter located within the center of each cerebral hemisphere; includes the caudate nucleus, lentiform nucleus, claustrum and amydala.
Part of the brain which controls movement. Includes the substantia nigra which produces dopamine, and striatum where dopamine is released.
Gray matter embedded in the white matter of the brain; involved with control of movement.
Groups of cerebral nuclei that play a role in the control and production of movement.
A group of brain areas that collectively are involved with control of normal movement and walking. The caudate nucleus and putamen (straitum), globus pallidus and substantia nigra are important basal ganglia structures.
several large clusters of nerve cells, including the striatum and the substantia nigra, deep in the brain below the cerebral hemispheres.
The nerve cells in the cerebrum which are concerned with coordination. Athetoid cerebral palsy may result from damage to the basal ganglia.
A series of structures located deep in the brain responsible for motor movements.
A group of structures and nuclei in the brain which help control movement.
A large group of nuclei deep within the brain that affects movement. The basal ganglia include the caudate nucleus, putamen, globus pallidus, subthalamic nucleus, and substantia nigra.
Clusters of neurons, which include the caudate nucleus, putamen, globus pallidus and substantia nigra, that are located deep in the brain and play an important role in movement. Cell death in the substantia nigra contributes to Parkinsonian signs.
The large gray mass at the base of the brain that coordinates movement
A collection of nerve cells at the base of the brain involved in the control of movement.
a region located at the base of the brain composed of four clusters of neurons, or nerve cells. This area is responsible for body movement and coordination. The neuron groups most prominently and consistently affected by HD--the pallidum and striatum--are located here. See neuron, pallidum, striatum.
an organ of the brain, belieto be involved in the modification of motor control. It is composed of the caudate nucleus, globus pallidus, and putamen, and is sometimes called the Lentiform nucleus. Some authors include the subthalamic nuclei and substantia nigra as part of a more general basal ganglia system, although these are anatomically distinct nuclei. The basal ganglia are sometimes called the "striatum."
specialized nerve cell clusters of gray matter deep within each cerebral hemisphere and the upper brainstem, including the striate body (caudate and lentiform nuclei) and other cell groups such as the subthalamic nucleus and substantia nigra. The basal ganglia consist of several large masses of gray matter embedded deep within the white matter of the cerebrum.
a region consisting of 3 clusters of neurons located at the base of the brain that are responsible for involuntary movements
Groups of neurons located deep within the brain that help control motor and cognitive activity.
A collection of masses of gray matter locateddeep within the brain that participate in emotion,cognition, and the regulation of motor performance.
Made up of the caudate nucleus and putamen (known together as the corpus striatum) and the globus pallidus. Roles in regulating movement and cognition. Damage to it causes seizure disorders, multiple-sclerosis-type disorders, decrement in intellectual capacity, judgment, ability to concentrate, memory, speech capability.
Structures deep in brainstem that relay messages between the prefrontal cortex and the lower motor and sensory areas
Blood-Brain Barrier BrainStem
The large, complex set of brain structures involved in generating movements, in some cognitive functions, and in some emotional and motivational activities. The basal ganglia and the cerebral cortex work together to refine movements, thoughts, and feelings.
Areas of the brain that are important from movement. These areas include the putamen, caudate nucleus, globus pallidus, subthalamic nucleus and substantia nigra.
Masses of nerve cells deep within the brain at the base of cerebral hemispheres.
A group of nerve cells located at the base of the brain. It is composed of the putamen, caudate, globus pallidus, and substantia nigra. (The putamen and caudate together make up the striatum.) The basal ganglia participate in the regulation of motor performance, among other things. (Singular form: basal ganglion.)
Large clusters of neurons deep within the brain that are responsible for voluntary movements such as walking and movement coordination. Includes the striatum, the subthalamic nucleus, and the substantia nigra
several large masses of grey matter embedded deep within the white matter of the cerebrum. They include the corpus striatum and the amygdaloid nucleus. The basal ganglia have complex neural connections with both the cerebral cortex and thalamus: they are involved with the regulation of voluntary movements at a subconscious level.
A group of structures at the base of the cerebral hemispheres, concerned with involuntary control of movement, among other functions.
groups of hundreds of thousands of neurons at the base of the cerebrum and in the upper brainstem; they help control well-learned movements (like walking) and sensation.
The basal ganglia are a group of nuclei in the brain interconnected with the cerebral cortex, thalamus and brainstem. Mammalian basal ganglia are associated with a variety of functions: motor control, cognition, emotions and learning.
