<p><b>A:</b> At each step of the single linkage algorithm clusters are merged on the basis of the minimum distance between two observations each belonging to separate clusters. Which observations were linked at each iteration of the algorithm (nodes of the above dendrogram) and at what distance they were from each other within the original pairwise distance matrix was used to generate an adjacency matrix or network that was then represented as a network graph. At each two dimensional coordinate the glyph summarizing the observations location within the response space to 4 chirp stimuli was plotted and a colored letter indicating On- (blue) or Off-type (red), deep (D), intermediate (I) or superficial (S) was plotted atop this. <b>B:</b> Same as A but for DTW. <b>C:</b> Response profiles captured by 44 response features projected into a three dimensional feature space using an 8 Factor statistical model (χ<sup>2</sup> = 1266 d.f. = 622 p = 3.47x10<sup>-46</sup>) accounted for 78% of the variance. Each observation is colored according to its anatomical designation and each observation is connected to the mean value of its anatomical class within the factor space. <b>D:</b> Network graph (desaturated black lines) constructed from an adjacency matrix where each observation was connected to the closest one half of the population using the warping distance between observations as entries with each mode labeled according to On- or Off-type as well as anatomical cell class. The mean coordinate for each of the six anatomical designations was computed and observations were linked to their respective groups mean.</p>
