Caption (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 ...

Synaptic vesicle docking and fusion are mediated by the assembly of a stable SNARE core complex of proteins, which include the synaptic vesicle membrane protein VAMP/synaptobrevin and the ...

Synaptic vesicles—sphere-like structures that store and release neurotransmitters such as dopamine and serotonin, are found in the presynaptic terminals of neurons. They play a crucial role in ...
