When studying neuroscience, one important concept is how neurons combine incoming signals before deciding whether to generate an action potential. Temporal summation and spatial summation are two mechanisms that allow postsynaptic potentials to combine. Although both help neurons integrate information, they differ mainly in timing and the number or location of inputs involved. What Is Temporal Summation? Temporal summation occurs when a single presynaptic neuron repeatedly sends signals in rapid succession to the same postsynaptic neuron. If the next signal…
