This explainer outlines how neurons and glial cells coordinate electrical and chemical signals to form complex brain networks that govern thought, behavior, and consciousness. It also explores how ...

in which an electrical signal triggers the release of neurotransmitters at a synapse, which in turn triggers a new electrical ...

There are two types of removal: Re-uptake – the neurotransmitter is reabsorbed back into the presynaptic neuron and restored inside a vesicle ready to be used again. For example, noradrenaline.

Synapses are subcellular microcompartments that are essential for a digital form of transneuronal communication, mediated by chemical mediators termed neurotransmitters. At excitatory synapses in ...

The action potential causes the release of molecules called neurotransmitters, which pass from one end of the synapse to the other. Once these molecules cross the synapse, the chemical signal is ...

Synapses are the connection points where neurons establish contact with each other to transmit information. For this ...

Neurons’ complex structures enable them to receive and transmit signals across synapses. McCabe’s team is interested in a specific part of this structure: the synaptic boutons, zones at the end of ...

Upon energy restriction, an unusual release of the neurotransmitter glutamate can be observed. The overabundance of glutamate ...

A fluorescent probe designed to incorporate a fluorophore into the structure of a neurotransmitter finds activity-dependent heterogeneity in dopamine release at individual synapses ...

Recreational drugs can affect neurotransmitters in the reward pathway within the brain. They can act as either agonists or antagonists. Recreational drugs can also stimulate the release of ...
