For real though. We already knew that neurons can do binary logic, they either fire or they don't and neurons higher up the chain fire based on converging input

For real though. We already knew that neurons can do binary logic, they either fire or they don't and neurons higher up the chain fire based on converging inputs. Also what do those plots actually 'show'. The authors claim repeatedly that the plots show the existence of 15 clusters, but without stating p values relating to any sort of classification for many of the plots.
