# 179 — Mutual inhibition of lateral inhibition: a network motif for an elementary computation in the brain

The circuit is dubbed “mutual inhibition of lateral inhibition” which is a bit cryptic. But it simply means that $n$ inputs, $I_0$, $I_1$, … $I_n$, are able to inhibit their neighbors ($I_1$ can inhibit $I_0$ and $I_2$) and that inhibitory circuit can in turn amplify the original signal by removing its neighbors’ inhibition. So if $I_1$ is very strong, $I_0$ and $I_2$ will be nearly silenced.
