Interactions between electrically induced attack and teeth-chattering from 1 electrode and grooming from another were examined in male albino rats. The interaction between electrically induced attack and deprivation-induced feeding, as well as the effect of food deprivation on attack, was also studied. Results indicate that attack appears to be a dominant response, for it suppressed grooming and feeding at a low level of activation. On the other hand, it was not affected by simultaneously induced grooming or feeding. However, food deprivation decreased the threshold for attack, leaving attack latency, attack form, or bite targets unaffected. Teeth-chattering, suggested to be related to attack and flight, was also a dominant response. Results suggest that interactions between behavioral systems are in favor of the systems that must act acutely on activation in order to survive. Apparently, the regulations governing these interactions are represented in the functional organization of the brain.
在雄性白化大鼠中，研究了来自一个电极的电诱导攻击与牙齿打颤以及来自另一个电极的梳理行为之间的相互作用。还研究了电诱导攻击与剥夺诱导进食之间的相互作用，以及食物剥夺对攻击的影响。结果表明，攻击似乎是一种主导反应，因为它在低激活水平时抑制了梳理和进食。另一方面，它不受同时诱导的梳理或进食的影响。然而，食物剥夺降低了攻击阈值，而攻击潜伏期、攻击形式或咬噬目标不受影响。牙齿打颤被认为与攻击和逃跑有关，也是一种主导反应。结果表明，行为系统之间的相互作用有利于那些为了生存必须在激活时迅速起作用的系统。显然，支配这些相互作用的调节机制体现在大脑的功能组织中。
