Definitions:

Temporal

Relating to time or denoting time as opposed to space.

Spatial Summation

A mechanism in neural communication where multiple presynaptic neurons together stimulate a postsynaptic neuron to threshold, causing it to fire an action potential.

Synaptic Terminal

The end part of an axon that makes a synaptic contact with another neuron or with a muscle or gland cell.

Voltage-Gated Potassium Channels

Proteins that form channels in cell membranes, allowing potassium ions to pass in response to changes in membrane potential, crucial for electrical signaling in neurons.
