(neuroscience)
A small membrane-bound structure in the axon terminals of nerve cells that contains neurotransmitters and releases them by exocytosis when an action potential reaches the terminal.

The researchers observed that when calcium levels in the nerve cell increase, such as upon neuronal signalling, the alpha-synuclein binds to synaptic vesicles at multiple points causing the vesicles to come together.
Given that spontaneous mEPSCs are believed to be the postsynaptic response to a single spontaneously released synaptic vesicle (Wiegert et al.
Timothy Ryan, professor of biochemistry at Weill Cornell Medical College, demonstrates that individual neurons somehow control the speed by which they recycle synaptic vesicles that store neurotransmitters before they are released.
When a pain signal is transmitted, the channel opens and the calcium concentration increases, triggering the release of neurotransmitters from synaptic vesicles, thereby sending the pain signal to the brain where it is perceived as pain.
The gene involved with EIC is responsible for making new synaptic vesicles and enabling nerve communication to continue.
Selective depletion of clear synaptic vesicles and enhanced quantal transmitter release at frog motor nerve endings produced by trachynilysin, a protein toxin isolated from stonefish (Synanceia trachynis).
The proteins produced in the nucleus are transported via microtubules and neurofilaments to the synapses that contain mitochondria, which are responsible for energy production, and the synaptic vesicles that store the different neurotransmitters (Figure 3).
It is worth noting that lipid-derived compounds do not have to be released from synaptic vesicles.
The postsynaptic terminals were seen to contain subsynaptic cisterns formed by membranes of smooth endoplasmic reticulum beneath the postsynaptic density, whereas the presynaptic terminal showed numerous electron transparent synaptic vesicles.
2+] dependent kinases, on releasing synaptic vesicles from actin filaments, may accelerate vesicles to the presynaptic membrane.
