The effects of medial preoptic area (MPOA), anterior hypothalamic (AH) and ventromedial hypothalamic (VMH) lesions on play fighting were studied in juvenile rats that were housed and observed in heterosexual groups of 6-8 animals. Overall males engaged in play fighting more frequently than females and none of the lesions reliably affected this measure. Males also initiated more play fights. AH and VMH lesions reduced the frequency of play initiation in both sexes, but MPOA lesions had no reliable effect in either sex.
在6 - 8只动物的异性混合组中饲养和观察的幼年大鼠身上，研究了内侧视前区（MPOA）、下丘脑前部（AH）和腹内侧下丘脑（VMH）损伤对嬉戏打斗的影响。总体而言，雄性比雌性更频繁地进行嬉戏打斗，且没有一种损伤能可靠地影响这一指标。雄性发起的嬉戏打斗也更多。AH和VMH损伤降低了两性嬉戏发起的频率，但MPOA损伤对两性均无可靠影响。
