Action Potential:A rapid rise and subsequent fall in membrane potential across a neuronal membrane, used for communication over long distances within the neuron.
Synapse:The junction between two neurons or between a neuron and a muscle cell, where electrical or chemical signals are transmitted from one cell to another.
Inhibitory Postsynaptic Potential (IPSP): A temporary hyperpolarization of postsynaptic membrane potential caused by the flow of negatively charged ions into the postsynaptic cell, making it less likely to fire an action potential
