alpha-CaMKII overexpressing mice display an increase in offensive aggression in the resident-intruder test. (A, B) offensive aggression. (C, D) defensive aggression. The latency to first attack bite (attack latency; A, C) and the number of attacks (B, D) are shown for alpha-CaMKII overexpressing (n = 10) and WT mice (n = 10). The asterisk indicates statistical significance at P < 0.05.
