Unit activity in the lateral hypothalamic area was recorded in rats after testing by the emotional resonance technique. The rats were divided in two groups by their reaction to the suffering cry of the partner ("victim"). Rats from the group I ("altruists") escaped ("victim") crying, and those from the group II ("egoists") did not. Activity of neurons was analysed in hungry rats, after feeding, after placing the "victim" into the experimental chamber, during intracranial emotionally positive and negative stimulation, and during crying of the "victim". The results showed that the majority of neurons of the rats from the I group responded to the partner's crying in the same way as to the intracranial emotionally negative stimulation and the reaction of the neurons of the rats from the II group was either poorly expressed or resembled that to the intracranial emotionally positive stimulation.
通过情感共鸣技术对大鼠进行测试后，记录其下丘脑外侧区的单位活动。根据大鼠对同伴（“受害者”）痛苦叫声的反应将其分为两组。第一组（“利他主义者”）的大鼠会在（“受害者”）哭泣时逃离，而第二组（“利己主义者”）的大鼠则不会。对饥饿的大鼠、进食后、将“受害者”放入实验箱后、颅内进行情感上的正性和负性刺激期间以及“受害者”哭泣期间的神经元活动进行了分析。结果表明，第一组大鼠的大多数神经元对同伴哭泣的反应与对颅内情感负性刺激的反应相同，而第二组大鼠神经元的反应要么表达微弱，要么类似于对颅内情感正性刺激的反应。
