What Is Spatial Summation - So now you are getting 4 stimuli occurring at once, each of them capable of raising the charge 5 mv. Tutorial 10 discusses the integration of postsynaptic potentials across both time and space. Web intro | spatial summation | temporal summation. Web spatial summation refers to stimuli from different sources occurring at a similar time. Return to main tutorial page. Web spatial summation occurs when stimuli are applied at the same time, but in different areas, with a cumulative effect upon membrane potential. Web spatial summation means that the effects of impulses received at different places on the neuron add up so that the neuron may fire when such impulses are received simultaneously, even if each impulse on its own would not be sufficient to cause firing. Each synapse brings sodium ions over the postsynaptic membrane, to cause a graded potential with localized effects. The closer a postsynaptic potential is to the decision point, the greater the influence it has on the eventual decision being made. This concept is called spatial summation.

Web imagine what happens to each of the psps shown as they travel over distance, or as time passes. Web spatial summation refers to stimuli from different sources occurring at a similar time. Web spatial summation occurs when stimuli are applied at the same time, but in different areas, with a cumulative effect upon membrane potential. Each synapse brings sodium ions over the postsynaptic membrane, to cause a graded potential with localized effects. The closer a postsynaptic potential is to the decision point, the greater the influence it has on the eventual decision being made. Spatial summation uses multiple synapses acting simultaneously. This concept is called spatial summation. Web spatial summation means that the effects of impulses received at different places on the neuron add up so that the neuron may fire when such impulses are received simultaneously, even if each impulse on its own would not be sufficient to cause firing.
