Neurotransmitter release is the process by which signaling molecules, known as neurotransmitters, are expelled from the presynaptic neuron into the synaptic cleft to transmit signals to a postsynaptic neuron. This essential process involves the fusion of synaptic vesicles with the presynaptic membrane, which is triggered by an influx of calcium ions following an action potential. The precise regulation of neurotransmitter release is crucial for communication within the nervous system and for maintaining homeostasis in various physiological processes.
