Positioned superior to the medulla oblongata and inferior to the midbrain, the pons acts fundamentally as a relay […]
Serotonergic Neurons: Role in Neurotransmission and Neuropsychiatric Disorders The Core Definition of Serotonergic Neurons Serotonergic neurons represent a specialized population of nerve cells within the central and peripheral nervous systems, defined primarily by their capacity to synthesize, store, and release the monoamine serotonin (5-hydroxytryptamine or 5-HT). These cellular units are fundamentally responsible for mediating the […]
