The space between the presynaptic and postsynaptic terminal, known as the synaptic cleft, is where the neurotransmitter crosses from the synapse of one neuron to the next.

Together, the presynaptic terminal, synaptic cleft and the receiving dendrite of a nearby nerve cell form a neuronal junction, also called a synapse. The synapse between a nerve and muscle cell is ...

Neurotransmitters, like glutamate, are important players, carrying signals across the synaptic cleft and driving processes like long-term potentiation —a fancy term for how synapses get stronger ...
