abstract：:Calcium influx through voltage-sensitive Ca2+ channels is the normal physiological stimulus for the activity-dependent release of neurotransmitters at synaptic contacts. It has been postulated that presynaptic inhibition of transmitter release is due to a reduction in Ca2+ influx at the nerve terminal, which could res...
