The role of beta-endorphin in regulation of instrumental food conditioning and in more complicated forms of nervous activity in cats was found to involve a facilitating unspecific effect both on positive and negative food conditioning, the latter having a general adaptive character. The influence of the same small doses of beta-endorphin (10 mkg/kg - 15 x 10(-6) mkg/kg) on the choice responses was more complicated and depended on the basic level of conditioning and the typology of animals. Possible mechanism of the beta-endorphin effect on higher nervous activity, is discussed.
已发现β-内啡肽在调节猫的工具性食物条件反射以及更复杂形式的神经活动中的作用，涉及对正向和负向食物条件反射的非特异性促进作用，后者具有一般适应性特征。相同小剂量的β-内啡肽（10微克/千克 - 15×10⁻⁶微克/千克）对选择反应的影响更为复杂，且取决于条件反射的基础水平和动物的类型。文中讨论了β-内啡肽对高级神经活动产生影响的可能机制。
