Definitions:

Exocytosis

The process by which cells release substances (such as neurotransmitters or hormones) to the exterior through fusion of vesicles with the plasma membrane.

Endocytosis

A cellular process in which substances are brought into the cell by engulfing them in an energy-using process.

Parallel After-discharge Circuit

A circuit configuration in neural networks that involves parallel paths with different lengths that can cause prolonged signal discharge.

Inhibitory Postsynaptic Potentials (IPSPs)

Hyperpolarizations occurring at a postsynaptic membrane making the neuron less likely to generate an action potential.
