"Summary: A new study has revealed how brain circuits and neurotransmitters regulate meal initiation, offering insights into obesity management.
Researchers identified serotonin neurons in the midbrain’s dorsal Raphe nucleus (DRN) as key players, inhibited by GABA and dopamine when hunger strikes. This inhibition lowers serotonin levels, triggering feeding behavior, while satiety reverses the process. Notably, GABA and dopamine synergize for more profound effects on serotonin suppression."
