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.

Hyperpolarization

An increase in the membrane potential of a cell, making the inside of the cell more negative relative to the outside and reducing the likelihood of firing an action potential.
