Neurotransmitter released by the marked structure:
Answer B. Dopamine
Structure marked in the image is – Substantia nigra
- The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement.
- Substantia nigra is Latin for “black substance”, reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons.
- Parkinson’s disease is characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta.
