At a chemical synapse, one neuron releases neurotransmitter molecules into a small space (the synaptic cleft) that is adjacent to another neuron. The neurotransmitters are contained within small sacs ...

Their 87-page chapter does an outstanding job of conjuring up the intellectual development of the synapse field ... a chapter by Tom Südhof on the synaptic cleft. As far as I know, there has ...

Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent continuous stimulation of postsynaptic neurons. There are two types of removal: Re-uptake – the ...

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