Which neurotransmitter is used in fiber from substantia nigra to corpus striatum
The neurotransmitter used in the fiber from substantia nigra to corpus striatum is dopamine.
The neurotransmitter used in the pathway from the substantia nigra to the corpus striatum is dopamine.
To find this answer, you can start by understanding the anatomy of the brain and the pathways involved in motor control. The substantia nigra is a small area located in the midbrain, and it plays a crucial role in initiating and controlling movement. It has two parts: the substantia nigra pars compacta (SNc) and the substantia nigra pars reticulata (SNr).
The fibers that extend from the substantia nigra pars compacta (SNc) to the corpus striatum are known as the striatal pathway. This pathway is involved in regulating voluntary motor movements, as well as in reward and reinforcement functioning.
The specific neurotransmitter used by the neurons in the substantia nigra pars compacta is dopamine. Dopamine is a chemical messenger that carries signals across synapses in the brain. It functions as a neurotransmitter in various brain regions involved in movement, motivation, and reward.
The loss of dopamine-producing neurons in the substantia nigra is strongly associated with Parkinson's disease, a neurodegenerative disorder characterized by movement difficulties.
To summarize, the neurotransmitter used in the pathway from the substantia nigra to the corpus striatum is dopamine. This information can be obtained by studying the anatomy and pathways involved in motor control in the brain.
