like vesicles at bona fide synaptic terminals. One reason for skepticism in evaluating factors that induce presynaptic differentiation in vitro is the evidence that non-specific factors ...

Hair trigger Neurons send each other signals by firing neurotransmitters across synapses. A stash of neurotransmitter-packed vesicles hunkers close to the presynaptic membrane so the vesicles can fuse ...

There are two types of removal: Re-uptake – the neurotransmitter is reabsorbed back into the presynaptic neuron and restored inside a vesicle ready to be used again. For example, noradrenaline.

To do this, the synaptic vesicle must dock at the membrane of the presynaptic neuron and dump its content into the synapse, where it moves to particular receptors on the postsynaptic neuron.
