Electrical stimulation of the lateral hypothalamus of rats maintained on a normal or salty diet with water deprivation leads to an increase in drinking excitability and to a decrease in the thresholds for salty food consumed. The stimulation promotes attenuation of the effects of the "mental" desalting of food that is achieved by a spatial co-placement of the nonsaltiness signal with salty reinforcement, and accelerates the conversion of the signal significance of the conditional stimuli associated with nonsalty and salty reinforcement as well. Electrical stimulation of the hypothalamus accelerates the formation of conditioned reflex aversion to salty food and the inhibition of conditioned reflexes in the direction of the corresponding food dispenser, and intensifies the existing state of thirst as well, imparting to it characteristics of a dominant motivation.
对正常饮食或高盐饮食且禁水的大鼠下丘脑外侧进行电刺激，会导致饮水兴奋性增加，以及食用咸味食物的阈值降低。该刺激促进了通过将无咸味信号与咸味强化物在空间上共同放置所实现的食物“心理”脱盐效应的减弱，并且还加速了与无咸味和咸味强化物相关的条件刺激的信号意义的转变。下丘脑的电刺激加速了对咸味食物的条件反射性厌恶的形成以及朝着相应食物分配器方向的条件反射的抑制，并且还强化了现有的口渴状态，使其具有主导动机的特征。
