Definitions for "Synapses"
provide functional links between neurons. Electrical activity of one neuron affects the activity of another by the release of chemicals (neurotransmitters) at their synapses.
the microscopic "contacts" between nerve cells that allow information to be passed from one cell to the next; for each synapse, a thin gap exists between the end of one axon and the surface of the neuron receiving the input; electrical impulses cannot "jump" across this gap, thus chemicals (or neurotransmitters) are used to cross the synapse and stimulate the recipient neuron; synapses can be either "excitatory" or "inhibitory", and stimulate or turn off the recipient neuron, respectively.
the gap between two neurons, over which impulses lead to learning
