The influence of the electrostimulation of "reward areas", preliminarily identified by the self-stimulation technique, on the evoked potentials recorded in the parafascicular complex of the thalamus in response to peripheral nociceptive stimulation was studied in 35 rabbits, of 41-60 days of life. When comparison was made of the data obtained with the results of studies carried out previously in adult animals and in rabbits from the 30th-40th days, in addition to common characteristics, features of these influences which were characteristics only for the age interval under investigation were distinguished. The antinociceptive influences of the "reward areas" on the evoked potentials in the parafascicular complex were less pronounced with respect to a number of parameters in the period of the rabbits life occupying the intermediate position between the over-excitable and adult periods of development.
在35只41至60日龄的家兔身上，研究了通过自我刺激技术初步确定的“奖赏区”电刺激对丘脑束旁复合体中记录到的、响应外周伤害性刺激的诱发电位的影响。当将所获得的数据与先前在成年动物以及30至40日龄家兔身上进行的研究结果进行比较时，除了共同特征外，还区分出了这些影响中仅在所研究年龄区间具有特征性的特点。在处于发育的过度兴奋期和成年期之间的家兔生命阶段，“奖赏区”对束旁复合体诱发电位的抗伤害性影响在一些参数方面不太明显。
