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

They should also be capable of trans-synaptic signaling and act to redistribute pre- and postsynaptic proteins. A prime example of such an inducer is agrin. A neuron-specific splice variant of ...

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 ...
