A sufficient local buildup of calcium causes postsynaptic NGF release [12] which then leads to an increase in presynaptic vesicle cycling.
The mechanism to suppress seizures of hypothermia is still unclear, maybe it is mediated by reducing Na [sup]+ exchange, decreasing K [sup]+ conductance, regulating glutamatergic synaptic transmission, reducing the release of presynaptic vesicle, and disrupting the synchronism of discharges.
Reserpine binds strongly to the VMAT receptor and prevents the neurotransmitters from being incorporated into the presynaptic vesicle.
