It takes just a few milliseconds: A vesicle, only a few nanometers in size and filled with neurotransmitters, approaches a cell membrane, fuses with it, and releases its chemical messengers into the ...

(1) A nerve impulse arrives. (2) This causes calcium ion channels to open, resulting in an influx of calcium ions in the terminal. (3) This causes synaptic vesicles to fuse with the terminal membrane, ...

Synaptic plasticity describes the biological process that enables learning and memory through facilitating changes in the connections between synapses. Interaction with the external world results in ...

Your brain doesn t just send messages through one universal route it uses separate pathways for spontaneous activity and signals linked to learning. These findings overturn a major neuroscience ...

It takes just a few milliseconds: A vesicle, only a few nanometers in size and filled with neurotransmitters, approaches a cell membrane, fuses with it, and releases its chemical messengers into the ...

Interactions of two voltage-gated calcium channels and a pump enable separate control of exocytosis and endocytosis at chemical synapses. Chemical synapses transmit information within the nervous ...
