Excitatory neurotransmitters increase the likelihood that a neuron will fire a signal called an action potential in the receiving neuron. There are several types of excitatory neurotransmitters.

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 ...

A neurotransmitter previously thought only to calm neurons may also play a role in waking them up, according to a study published in the journal PLOS Biology, a discovery which challenges the textbook ...

The researchers observed that the neonatal mouse gut had much higher levels of neurotransmitters, including serotonin, than the adult gut. "So far, almost all studies of gut neurotransmitters were ...

Scientists at St. Jude Children’s Research Hospital have drawn on structural biology expertise to determine structures of vesicular monoamine transporter 2 (VMAT2), a key component of neuronal ...

For neurons to communicate, proteins have to get involved. One of the jobs these proteins have is to get neurons to release molecules called neurotransmitters. These chemical messengers are what gets ...
