How can I explain neuron synapse and what it does in the simplist possible terms? I've read & read, and I semi-understand but I have no idea how to explain it to someone else.

Neurons connect to each other at synapses. The electrical impulses, however, don't simply jump from neuron to neuron. Instead when the impulse reaches the end of the axon, it releases tiny packets of a chemical called a neurotransmitter, which diffuses across a microscopic gap and stimulates a new nerve impulse at the connecting neuron. Because of this electrical-to-chemical-to-electrical chain, a great deal of fine control is possible. For instance, there must be a threshold amount of neurotransmitter to transmit an impulse. And some neurons can secrete inhibitory rather than stimulatory chemicals, allowing multiple neurons to ' vote ' on whether an impulse is transmitted. Thus a simple arrangement enables complex behavior.
