Serotonin, also known as 5-hydroxytryptamine, is a neurotransmitter - a chemical substance that transmits nerve impulses across the space between nerve cells or neurons - known as a synapse. It plays ...

Also referred to as chemical messengers, neurotransmitters are chemical agents made and released by neurons. They are stored in vesicles at the terminal end (presynaptic terminal) of a neuron. Their ...

Stanford University researchers developed a tissue-mimicking, stretchable sensor termed NeuroString for real-time measurement of neurotransmitter dynamics in vivo in the brain, gut, and other soft ...

Receptors on the postsynaptic membrane determines whether the signal received is: However, a series of weak stimuli can combine, increasing the amount of neurotransmitter that is released. This ...

Research at Robarts Research Institute in London has found that having too much of a particular neurotransmitter may be good for the muscles but not for the brain. Researchers were looking into ...

An electrical impulse cannot directly cross the gap so a different mechanism has to be used. Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent ...

Discover how dopaminergic terminals in the nucleus accumbens co-release glutamate, impacting pleasure and motivation. Important news from San Francisco neuroscientists Stuber et al: Dopaminergic ...

Aromatic amino acid decarboxylase (AADC) deficiency is a rare, autosomal recessively inherited neurometabolic disorder characterised by markedly reduced synthesis of key monoamine neurotransmitters ...
