Serotonergic neurons are located in the brain stem raphe nuclei and give rise to a broad system of axonal projections. They have a slow, rhythmic firing pattern, which is greatest during alert …

Serotonergic action is terminated primarily via uptake of 5-HT from the synapse. This is accomplished through the specific monoamine transporter for 5-HT, SERT, on the presynaptic …

We review recent findings that have revealed the molecular basis for the tremendous diversity of 5-HT neuron subtypes, the impact of environmental factors on 5-HT neuron development, and …

Serotonergic neurons, often referred to as serotonin neurons, are a specialized neuronal population that utilizes the neurotransmitter serotonin (5-HT) to communicate within the central …

Jul 28, 2025 · Serotonergic pathways refer to the complex networks of neurons that produce, transmit, and receive serotonin signals throughout the body. The process begins with the …

Feb 22, 2025 · Serotonergic neurons display a spectrum of firing patterns intricately linked to various behaviors, yet uncovering the precise impact of these firing activities on serotonin …

Dec 18, 2014 · Now, thanks to new genetics tools, Harvard Medical School researchers and their collaborators have identified many different molecular subtypes of serotonergic neurons in …

The serotoninergic system refers to the network of serotonergic neurons, primarily located in the raphe nuclei of the brainstem, that is involved in regulating various functions within the central …

May 23, 2024 · Serotonin is synthesized from tryptophan in small groups of neurons within the central nervous system. These neurons, however, branch profusely and innervate all the …

Jul 24, 2025 · After synthesis, serotonin is stored within small sacs called vesicles inside specific neurons. When an electrical signal, or action potential, arrives at the end of a serotonin …
