How do we think, feel, remember, or move? These processes involve synaptic transmission, in which chemical signals are ...

Inside each neuron, electrical impulses travel rapidly, while communication between neurons takes place across microscopic gaps called synapses. At these junctions, neurotransmitters like dopamine ...

Neurons do not actually touch. Each axon produces about 160 different neurotransmitters that cross a minuscule gap, the synapse, to insert themselves in the receptors of dendrites that are ...

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

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and ...

The third study, led by Marc Freeman of Oregon Health Sciences University in Portland, reported that norepinephrine rendered astrocytes more reactive to other neurotransmitters, including dopamine.

A neuron is a type of cell that specializes in communicating with other cells by sending out chemical signals, called neurotransmitters, into synapses. In the brain, there are 100 trillion ...

A small percentage were empty. Staining for astrocyte markers revealed it was this cell type that filled most synaptic pockets, implying astrocytes might be cleaning up neurotransmitters after the ...

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 ...
