Fig. Appendix Figure 9 Hunting behavior reorganizes neurons in the functional space (continued on next page). Rows correspond to five light-field recordings of zebrafish engaged in hunting behavior: fish 1 to fish 5. (A, D, G, J, M) (top) Functional space organization of the control data inferred by fitting the ERM and MDS (Result). Neurons are clustered using the Gaussian Mixture Models (GMMs) and their cluster memberships are shown by the color. The colorbar represents the proportion of neurons belonging to each cluster. (A, D, G, J, M) (bottom) The coordinate distribution of the cluster in control data which is most dispersed (i.e., largest fold change in size, see below) after hunting-removal. The transparency of the dots (colorbar) is proportional to the probability of the neurons belonging to this cluster (Appendix 1). The cyan ellipse serves as a visual aid for the cluster size: it encloses 95% of the neurons belonging to that cluster (Appendix 1). (B, E, H, K, N) (top) Similar to (A, D, G, J, M) (top) but the functional coordinates are inferred from the hunting-removed data. The color code of each neuron is the same as that in the control data, which allows for a comparison of the changes to the clusters under the hunting-removed condition. (B, E, H, K, N) (bottom) Similar to (A, D, G, J, M) (bottom) but the functional coordinates are inferred from the hunting-removed data. The transparency of each neuron is the same as in (A, D, G, J, M). (bottom), and it represents the probability pik (Appendix 1) of neurons belonging to the most dispersed cluster k in the control data. Likewise, the cyan ellipse encloses 95% of the neurons belonging to that cluster (Appendix 1). (C, F, I, L, O) Top, size/area fold change (Appendix 1) for each cluster (the gray dashed line represents a fold change of 1, i.e., no change in size); bottom, the anatomical distribution of the neurons in the most dispersed cluster.
