WebAfter neurotransmitters deliver their message, the molecules must be cleared from the synaptic cleft (the space between the nerve cell and the next target cell). They do this in one of three ways. Neurotransmitters: Fade away (a process called diffusion). Are reabsorbed and reused by the nerve cell that released it (a process called reuptake).
