Blood pressure and heart rate were monitored continuously in five dogs for 1 hour before performance on a free-operant shock-avoidance task. Cardiovascular changes during the preavoidance hour were characterized by sustained and significant increases in blood pressure, and sustained and significant decreases in heart rate.
在五只狗执行自由操作的电击回避任务前1小时,持续监测其血压和心率。在回避前的1小时内,心血管变化的特征是血压持续显著升高,心率持续显著下降。
