Dietary amino acid regimens designed to enhance catecholaminergic and serotonergic functioning were found to differentially affect territorial-induced attacks in mice. Male albino mice were maintained on a semi-synthetic 12% casein protein diet for 2 weeks, then switched to diets modified by the addition of a 4% L-amino acid supplement, or 4% casein (control). Measures of aggressive behavior and open-field locomotor activity were obtained before and after the dietary supplements were administered. Resident mice fed supplements of L-tyrosine displayed a marked increase in the number of attacks on intruders and shorter attack latencies, but their locomotor activity was unaffected. L-phenylalanine supplements alone or in combination with L-tyrosine reduced the latency to attack and increased motility but did not affect the number of attacks. As a whole, the group of animals fed L-tryptophan showed no changes in aggression or motility.
旨在增强儿茶酚胺能和血清素能功能的饮食氨基酸方案被发现对小鼠领地诱导的攻击行为有不同影响。雄性白化小鼠先在半合成的12%酪蛋白蛋白质饮食中维持2周，然后切换到添加4% L - 氨基酸补充剂或4%酪蛋白（对照）的改良饮食。在给予饮食补充剂之前和之后，获取攻击行为和旷场运动活动的测量值。喂食L - 酪氨酸补充剂的常驻小鼠对入侵者的攻击次数显著增加，攻击潜伏期缩短，但它们的运动活动未受影响。单独的L - 苯丙氨酸补充剂或与L - 酪氨酸联合使用可缩短攻击潜伏期并增加运动能力，但不影响攻击次数。总体而言，喂食L - 色氨酸的动物组在攻击性或运动能力方面没有变化。
