Hierarchical clustering of all strongly responding tectal neurons ( n =7,094) to identify functional cell types (f-types). Left, dendrogram of clustering all 169 exemplars that were identified using affinity propagation. Middle, heat map showing response vectors of all exemplars based on visual stimuli. Functional clusters and exemplars are primarily divided into local (clusters 14 and 1517) versus global (clusters 514) motion responses. Right, raw calcium traces of all exemplars.
