b. spatial summation
c. synaptic summation
d. saltatory summation
Final answer: Sherrington found that repeated stimuli within a brief time have a cumulative effect.

Sherrington found that repeated stimuli within a brief time have a cumulative effect, known as temporal summation.

Sherrington's discovery of temporal summation shed light on an important mechanism in neuronal communication. Temporal summation occurs when the same stimulus is repeatedly applied to a neuron within a short period of time. This results in the accumulation of signals, eventually triggering an action potential.

This phenomenon plays a crucial role in increasing the strength of synaptic connections. By allowing signals to build up over time, temporal summation enhances the effectiveness of neuronal communication and information processing.

Understanding temporal summation is essential in unraveling the intricate processes that govern the functions of the nervous system. It showcases the dynamic nature of neuronal responses and highlights the significance of timing in signal transmission.
