An area has been marked in the coronal section of the brain below. Defect in this area will lead to what pathology?
Answer- C. Paralysis agitans
- The area marked with the star is a dark, blackish area in the region of mid-brain, which represents substantia nigra.
- Lesions of substantia nigra produce Parkinson’s disease, also called paralysis agitans.
- Paralysis agitans, which means “shaking palsy,” is another term used for Parkinson’s disease. In Parkinson’s disease, the levels of dopamine in the substantia nigra and striatum decrease dramatically as a result of the degeneration of pars compacta neurons.
