It is known that the lesion of the nigrostriatal and pallidofugal systems causes an experimental condition comparable to the hypothalamic sindrome, with severe aphagia and adipsia. It was considered of interest to study the effects of the low frequency long-duration stimulation of the substantia nigra and the globus pallidus on feeding behaviour. Experiments were performed on eight chronic cats with electrodes implanted in SN (pars compacta) and in the GP (pars externa). In the 2 hours of observation the food intake and the number of food-taking acts were calculated. The stimulation was induced continuously in the former hour. The modification in food intake, also on the basis of somatic behavioural observations may be ascribed to motor impairment rather than to involvement of a motivational state.
已知黑质纹状体系统和苍白球传出系统的损伤会导致一种与下丘脑综合征相当的实验状态，伴有严重的摄食不能和饮水不能。研究黑质和苍白球的低频长时间刺激对摄食行为的影响被认为是有意义的。对八只慢性猫进行了实验，电极植入黑质（致密部）和苍白球（外部）。在两小时的观察期内，计算食物摄入量和进食行为的次数。在前一小时持续进行刺激。食物摄入量的改变，同样基于躯体行为观察，可能归因于运动障碍而非动机状态的参与。
