known as the synaptic cleft. (4) The neurotransmitters bind to receptor sites on ion channels in the postsynaptic membrane, causing them to open. (5) Ions flow into the postsynaptic neuron ...

Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent continuous ... reabsorbed back into the presynaptic neuron and restored inside a vesicle ready ...

By influencing calcium homeostasis, local protein synthesis and the endoplasmic reticulum, a small protein called Rab10 emerges as a crucial cytoplasmic regulator of neuropeptide secretion.
