(A) Normalized calcium transients of all exemplars (gray) and average transients of all cells (colored) for the 14 tectal clusters. (B) Validation of cluster number by the silhouette coefficient. A minimal number of 14 clusters was chosen (dashed blue line). (C) 3D representation of the three main principal components (PCs) for all tectal cells. Data points are colored by their corresponding cluster. (D) The chosen number of three PCs explains 74.9% of the variance in the measured data (black curve). Shuffled data (blue curve) resulted in a lower average explained variance (57.6% for the three main PCs). (E) Functional cluster distribution of superficial interneurons (SINs) and neuropil interneurons (NINs), imaged in the elavl3:nls-GCaMP6s line (n = number of cells from three fish). Cluster numbers are indicated.
