Spike Code Flow in Cultured Neuronal Networks

Table 2

Normalized maximum cross-correlation of to the next frame () between the different codes and of Table 1. The italic data shows values less than 1. By the normalization making the diagonal components 1, we can see more than half of the nondiagonal components are less than 1, and this means that statistically each code flows independently from other codes.
