Basal ganglia

Definition

The basal ganglia are a group of nuclei in the brain involved in regulating voluntary motor movements, procedural learning, and emotions. They play a crucial role in coordinating smooth and precise muscle activity.

5 Must Know Facts For Your Next Test

1. Basal ganglia dysfunction can affect motor control, leading to conditions like Parkinson's disease.
2. Proper nutrition impacts neurotransmitter synthesis, which is vital for basal ganglia function.
3. Omega-3 fatty acids have been shown to support basal ganglia health and improve motor functions.
4. Excessive saturated fats may impair basal ganglia function and contribute to neurodegenerative diseases.
5. Antioxidants from fruits and vegetables can protect the basal ganglia from oxidative stress.
