26 sie 2018 · The dorsal raphe (DR) constitutes a major serotonergic input to the forebrain and modulates diverse functions and brain states, including mood, anxiety, and sensory and motor functions. Most functional studies to date have treated DR serotonin neurons as a single population.
20 lut 2024 · Functions: It’s responsible for higher brain functions, including thought, action, emotion, and interpretation of sensory data. Effects of Damage: Depending on the area affected, damage leads to memory loss, impaired cognitive skills, changes in personality, and loss of motor control.

For example, the frontal cortex receives heavy innervation from the rostral and lateral subregions of the dorsal raphe nucleus. Raphe neurons send collateral axons to areas of brain that are related in function, such as the amygdala and hippocampus or the substantia nigra and caudate putamen.

5 paź 2022 · In the brain, serotonin changes mood, anxiety, and happiness by increasing nerve stimulation and electrical impulses. Drugs like ecstasy and LSD increase the levels of serotonin in the brain to produce effects like increased appetite, increased sexual drive, euphoria, and even hallucinations.
