About this clipart
The image depicts a sagittal section of the human brain with labeled regions critical to motor control, including the substantia nigra, caudate nucleus, putamen, and striatum. In Parkinson’s patients, dopamine-producing neurons in the substantia nigra degenerate, impairing the nigro-striatal pathway and resulting in hallmark motor deficits like bradykinesia and rigidity. The diagram emphasizes the functional circuitry disrupted in neurodegenerative movement disorders.
Used in medical education, neurology articles, or patient resources explaining Parkinson’s pathophysiology; targets users seeking to understand brain anatomy linked to movement disorders, diagnosis, or treatment mechanisms.
