Spike Code Flow in Cultured Neuronal Networks

Figure 11

Maximum cross-correlation that is normalized by the code duration for 14 major codes of Sample A. The values are calculated from the EShuf/Org ratios of each code. This graph can be considered as another spectrum concerning the flow property of major codes. We can see that the normalized spectrum has flat (white) characteristic. That is, each major code can be considered as relatively independent. Though the values of itself are larger than , flow property difference between the original train and shuffled one of is significantly larger than that of as seen from value.
