Seven types of ILD functions observed. Typical four ideal ILD functions (Figure 8) can easily be perceived among these seven type of ILD functions here; what makes the another three “transitional” cluster findings is significantly important in this study. Type of ILD functions are derived from each clustered data by averaging their objects. All maximum numbers of mean spike counts is scaled up to 45 for a comparison reason. For example, The Cluster-4 shows peak type ILD functions by averaging its (25) objects where the Cluster-6 also shows arisen-peak ILD functions by averaging its (11) objects. These numbers of objects are also shown in Figure 9.
