| Popis: | Classically conditioned heart-rate deceleration was established in rats using a 2-sec stimulation of the intact cervical vagus nerve as the US. Although small in magnitude, changes in the form of the CR over training indicated that there may have been inhibition of delay similar to that obtained using a traditional painful shock US. Independent assessments of motivational potency revealed that the vagal US did not lead to conditioned lever-press suppression in a CER procedure, but did produce reliable escape responding in a shuttle-box preference situation. It was suggested that the mildly aversive motivational effects of vagal stimulation may have stemmed from the activation of a vagally mediated system involved in the regulation of hunger. |
