Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent continuous ... Re-uptake – the neurotransmitter is reabsorbed back into the presynaptic neuron ...

releasing neurotransmitter into the gap between neurons, known as the synaptic cleft. (4) The neurotransmitters bind to receptor sites on ion channels in the postsynaptic membrane, causing them to ...

Electrophysiological studies, as well as light, fluorescence and electron microscopy approaches, have advanced our understanding of the functional and morphological characteristics of synaptic ...

This results in enough neurotransmitter being diffused across the synaptic cleft to trigger the impulse in the postsynaptic neuron. This process is called summation.
