WebIn temporal summation, two stimuli, each being too weak to excite, cause a sensation of light if presented in rapid succession on the same spot of the retina; thus, over a certain range of times, up to 0.1 second, the Bunsen-Roscoe law holds: namely, that the intensity of light multiplied by the time of exposure equals a constant. Thus it was found that within … Web20 Jan 2024 · Spatial summation. The temporal summation occurs when there is the repetitive firing of a single neuron.

Temporal summation describes the influence of stimulus duration on its visibility . It occurs because a longer duration stimulus emits more photons over time than a brief stimulus of the same intensity. Multiple, sequential photons may be required for the light to be seen. 4.
