Chemical neurotransmitters move across the gaps from the presynaptic ending of the axon to the postsynaptic membrane of the adjoining dendrite. These chemical messengers then either excite or inhibit electrical activity in the postsynaptic cell. Via their synaptic connections, brain

Synaptic pruning, a phase in the development of the nervous system, is the process of synapse elimination that occurs between early childhood and the onset of puberty in many mammals, including humans. Pruning starts near the time of birth and continues into the late-20s. During pruning, both the axon and dendrite decay and die off.
