Significant results of the PCA performed on the main parameters measured in the behavioral and gene expression experiments.

The first component includes cholinergic markers, olfactory reaction to social odor, distance covered in the 3-chamber task and latency to react t a threatening stimulus in the looming task. The second component includes durations of social contact in the SIT, the number of follow episodes and the frequency of USVs. Absence of value indicates no correlation with PCA scores.
