The process by which multiple neural inputs from different locations are combined at a single neuron, influencing its output.

Temporal Summation

A process by which multiple subthreshold signals can combine over time to trigger a significant response in a neuron.

Refractory Periods

Time intervals following an action potential during which a neuron is incapable of firing again or the threshold for firing is significantly raised.
