Pontine Raphe Magnus Serotonergic Neurons is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The raphe magnus (RMg) is a midline brainstem nucleus that provides serotonergic innervation to the spinal cord and brain. These neurons are involved in pain modulation, breathing, and are affected in neurodegenerative diseases.
| Marker | Function |

| TPH2 | Tryptophan hydroxylase 2 |
| SERT | Serotonin transporter |
| 5-HT1A | Autoreceptor |
| 5-HT2A | Postsynaptic receptor |
| Drug | Mechanism | Clinical Use |
|---|---|---|
| Fluoxetine | SSRI | Depression |
| Trazodone | 5-HT2 antagonist | Insomnia |
| Buspirone | 5-HT1A partial agonist | Anxiety |
