What is the process by which a single synapse receives many EPSPs in a short period of time called?

The process described, where a single synapse receives multiple excitatory postsynaptic potentials (EPSPs) within a short timeframe, is known as temporal summation. This phenomenon occurs when successive signals arriving at the same synapse contribute to a cumulative effect. If these EPSPs occur close enough together in time, their amplitudes can add together, potentially reaching the threshold needed to trigger an action potential in the postsynaptic neuron.

Temporal summation highlights the importance of the timing of synaptic inputs and demonstrates how rapid successive stimulation at a synapse can enhance neuronal communication. This process is crucial for the integration of synaptic signals, allowing for dynamic responses to stimuli. It contrasts with spatial summation, which involves the simultaneous input of EPSPs from multiple synapses located on the same neuron, and the other options mentioned pertain to different aspects of synaptic function or neurotransmission rather than the specific accumulation of EPSPs over time.
