Basal Ganglia: What It Is, Function & Anatomy - Cleveland Clinic
2022年8月5日 · The basal ganglia (pronounced “bay-sal” “gang-lee-uh”) are a group of structures near the center of your brain that form important connections. These connections allow different areas of your brain to work together. The basal ganglia manage the signals your brain sends that help you move your muscles.
Basal Ganglia Brain Damage: Causes, Symptoms, & Treatment
2022年4月4日 · The basal ganglia are structures within the brain primarily responsible for movement. When someone sustains basal ganglia brain damage, they may experience difficulties with balance, posture, or other movements. Normally, the brain is in constant communication with your muscles via neural pathways.

Functions and dysfunctions of the basal ganglia in humans
Lesions in the basal ganglia or the cerebellum show distinctly different motor symptoms and signs either by neurodegenerative diseases or local lesions by trauma, neoplasm, or vascular disorders. However, in various movement disorders with affects of the basal ganglia, an increase in metabolic activity in the cerebellum has been reported recently.

2024年6月13日 · Basal ganglia dysfunction is a problem with the deep brain structures that help start and control movement. Any condition that can cause brain injury can damage the basal ganglia. Such conditions include: A common cause of the symptoms of basal ganglia dysfunction is chronic use of medicines called antipsychotics, used to treat schizophrenia.
Basal ganglia disease - Wikipedia
Basal ganglia disease is a group of physical problems that occur when the group of nuclei in the brain known as the basal ganglia fail to properly suppress unwanted movements or to properly prime upper motor neuron circuits to initiate motor function. [1]
Anatomy, Physiology, and Clinical Syndromes of the Basal Ganglia…
In this article, we summarize the anatomy and physiology of the basal ganglia and cerebellum, and briefly highlight the clinical syndromes that may arise in the context of their injury or dysfunction. The basal ganglia (BG) are subcortical structures primarily involved in motor control and motor learning.
