Synaptische summation
WebThere are four steps (from 1 a 4) adding the only value 2. The next example shows a more sophisticated (and even more useful) use of summations. The summation term is a function: (2x 1 -1)+ ( 2x 2 -1)+ ( 2x 3 -1)+ ( 2x 4 -1) = 1+3+5+7 = 16. Note that each step of the sum uses the value of i and replaces it in function 2i – 1.

Summation facilitation is when a neuron is more likely to fire due to the combined excitatory and inhibitory inputs, creating a positive …
WebSep 22, 2004 · If summation was linear, the sum of the two separate EPSPs (EPSP(h) + EPSP(t)) should be the same as the EPSP produced when the two pathways were stimulated together (EPSP(h + t)). Especially at higher stimulus intensities, summation was not linear, and an example is shown in Fig. 6C in which the linear sum of the two EPSPs is larger …
