What is basal ganglia radiology?
The basal ganglia are a group of grey matter nuclei in the deep aspects of the brain that is interconnected with the cerebral cortex, thalami and brainstem. In a strict anatomical sense, it contains three paired nuclei that together comprise the corpus striatum: caudate nucleus. lentiform nucleus. putamen.
What does the basal ganglia look like?

What are basal ganglia?
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.
What part of the brain is the basal ganglia?
The structures generally included in the basal ganglia are the caudate nucleus, putamen, and globus pallidus in the cerebrum, the substantia nigra in the midbrain, and the subthalamic nucleus in the diencephalon. The word basal refers to the fact that the basal ganglia are found near the base, or bottom, of the brain.
Is basal ganglia involved in memory?
Extensive evidence now indicates a role for the basal ganglia, in particular the dorsal striatum, in learning and memory. One prominent hypothesis is that this brain region mediates a form of learning in which stimulus-response (S-R) associations or habits are incrementally acquired.
How common is basal ganglia stroke?
Basal ganglia stroke is a rare type of stroke that can lead to unique long-term effects, like emotional blunting or loss of spontaneous speech.
What are the symptoms of a basal ganglia stroke?

- numbness or weakness on one side of the face or the body.
- a lack of coordination or balance.
- difficulty speaking or understanding words spoken to you.
- difficulty seeing out of one or both eyes.
What is the function of the basal ganglia?
The subcortical basal ganglia nuclei receive information from the cortex and send output to the thalamus
What does basal ganglia stand for?
Basal ganglia (Corpus striatum) The basal ganglia, or basal nuclei, are a group of subcortical structures found deep within the white matter of the brain.They form a part of the extrapyramidal motor system and work in tandem with the pyramidal and limbic systems.. The basal ganglia consist of five pairs of nuclei: caudate nucleus, putamen, globus pallidus, subthalamic nucleus, and substantia
Where is the basal ganglia located?
Anatomy and connections. Anatomically,the basal ganglia consist of parallel complementary pathways that process motor,limbic,sensory,and associative information.
