Microglia-depleted animals exhibit decreased fear and avoidance but display risk-assessing behaviors. Quantification of data from the predator odor exposure test (PN33) for time (in seconds) spent in various behaviors including time behind the barrier (a), freezing behavior (b), stretch-attend behavior (c), stretch-locomotion behavior (d), number of stimulus cloth approaches (e), and stimulus cloth interaction duration (f). Bars indicate group means ± SEM for VEH-treated (black) and LC-treated (green) rats of both sexes. Open circles represent data from individual rats. *p < 0.05, **p < 0.01, ***p < 0.001. n = 18–20 per treatment.
