Lesions of the habenular-paraventricularis-anterior complex of the thalamus caused a total impairment of conditioned avoidance response of hooded rats (Long-Evans-strain) in a jumping test, but not in a simple runway. The change of stereotyped avoidance reactions could be attained very slowly. Running speed was lower and the number of errors much higher using an alternation schedule. Lesions of the nucleus centralis medialis and partly of its surrounding caused less deficits. From the results may be suggested that regulatory interactions between general behavioural activation originating from the brain stem, motivational processes and the analyzer systems are disrupted.
丘脑缰核-室旁核-前复合体的损伤导致带帽大鼠(长-伊文斯品系)在跳跃试验中条件性回避反应完全受损,但在简单跑道试验中未受损。刻板回避反应的改变非常缓慢才能出现。采用交替程序时,奔跑速度较低,错误数量高得多。内侧中央核及其部分周围区域的损伤造成的缺陷较少。从这些结果可以推测,源自脑干的一般行为激活、动机过程和分析系统之间的调节相互作用被破坏。
