采用时间条件反射和固定时间间隔的按压法研究了奖励性脑刺激对大鼠吸气率的影响。在早期的时间条件反射试验中，吸气频率在脑刺激后最明显。通过条件反射，吸气频率在大脑刺激之前变得最明显。在这项研究的两个实验中，嗅闻范围内的灵感频率仍然是对奖励性脑刺激的无条件反应的一部分。在固定间隔程序中，吸气频率在间隔的第一次按压前增加，并继续增加，直到提供强化。这些结果表明，呼吸/嗅频率的测量可能与经典的条件反射解释的动机行为。
The effect of rewarding brain stimulation on inspiration rate in the rat was investigated using a temporal conditioning and a fixed-interval lever-pressing procedure. In early temporal conditioning trials, inspiration frequency was most pronounced following brain stimulation. With conditioning, inspiration frequency became most pronounced preceding brain stimulation. Inspiration frequency in the sniffing range remained part of the unconditional response to rewarding brain stimulation throughout both experiments of this study. In the fixed-interval procedure, inspiration frequency increased just prior to the first lever-press of an interval, and continued to increase until reinforcement was delivered. These results suggest that measurement of respiration/sniffing frequency may have relevance to classical conditioning interpretations of motivated behavior.
