bouton at the tip of a nearby neuron. Note that neurons never actually touch each
other. Synapses typically transmit signals one-way, from bouton to receptor, in
contrast to electrical conductors, which are bidirectional.
Dendrites, Soma, Axon Hillock, Axon
Pulses triggered in dendrites propagate according to the logic they undergo,
traveling to the body or soma, where various incoming pulses may build up a
charge. Once charge surpasses a threshold for triggering, pulses propagate from the
