Definitions:

Back Propagation

Reverse movement of an action potential into the soma and dendritic field of a neuron; postulated to play a role in plastic changes that underlie learning.

Action Potential

A temporary reversal of an electric polarization of the membrane of a nerve cell or muscle cell, allowing for the transmission of signals.

EPSP Reversal

A phenomenon where the excitatory postsynaptic potential changes direction, usually due to alterations in ion gradient or membrane potential.

Neural Plasticity

The ability of the brain's neural networks to change through growth and reorganization, in response to learning or experience.
