When multiple sub stimuli converge on one cell body simultaneously, this is known as?

Explanation:
When several inputs arrive at different locations on the same neuron at the same time, their graded potentials combine at the cell body to produce a larger net depolarization. This is spatial summation. It differs from temporal summation, where the same synapse fires repeatedly in quick succession and the resulting potentials add up over time. Remember, even with summation, the combined signal must reach the threshold to trigger an action potential; if it doesn’t, no spike occurs.
