Scientists show that serotonin activates brain areas influencing behavior and motivation

Using light stimulation and MRI, scientists compared the effects of stimulating the brain’s serotonin center in awake and anesthetized mice, showing a clear difference in activation levels between the two states. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-48489-6 Our brains are made of tens of billions of nerve cells called neurons. These cells communicate with each other through biomolecules called neurotransmitters. Serotonin, a type of neurotransmitter, is produced by serotonin neurons in our brains and influences many of our behavioral and cognitive functions such as memory, sleep, and mood.
