The vesicles themselves inside the giant synapse are not larger, but it is much easier to follow their individual paths within the huge synapse. The real challenge was to establish a method to ...

The vesicle cycle describes the steps through which neurotransmitters (chemical signals) are released at a synapse (a junction between nerve cells), to transfer information between cells.

The process of recycling at a synapse. First, lipid membrane capsules are recovered from the pre-synaptic terminal membrane. Then, the vesicles are refilled with neurotransmitter.

When the vesicles merge into the membrane and release their chemical cargo, the neurotransmitters float across the open synapse to the next neuron. This happens every time the neuron “fires.” ...

But vesicle fusion is thought to be triggered by the much higher Ca 2+ concentrations (more than 100 μM) near the open mouth of individual Ca 2+ channels 6 . It now appears 2 , 3 that such high ...

The recycling pool consists of all vesicles stained with fluorescent dye when the synapse is stimulated at 10 Hz for one minute, a procedure that leads to saturated labeling of synapses 11,12 that ...

T here is very little about membrane vesicle fusion that Yale University biochemist James Rothman doesn’t know—he codiscovered SNAREs, the proteins that orchestrate the process. But one unanswered ...
