Nucleus raphe pallidus
Nucleus Raphe Pallidus
The Nucleus Raphe Pallidus (NRP) is a cluster of neuronal cells located in the brainstem. It is part of the raphe nuclei, a group of nuclei found in the brainstem that are primarily involved in the release of serotonin.
Anatomy[edit | edit source]
The Nucleus Raphe Pallidus is located in the medulla oblongata, a part of the brainstem. It is situated near the midline, adjacent to the superior olivary complex. The NRP is one of the seven nuclei that make up the raphe nuclei.
Function[edit | edit source]
The Nucleus Raphe Pallidus plays a crucial role in the regulation of autonomic functions. It is involved in the control of cardiovascular and respiratory systems, as well as in the regulation of body temperature. The neurons in the NRP release serotonin, a neurotransmitter that is involved in the regulation of mood, appetite, and sleep.
Clinical Significance[edit | edit source]
Alterations in the function of the Nucleus Raphe Pallidus have been associated with several neurological and psychiatric disorders, including depression, anxiety disorders, and Parkinson's disease.
