Conditioned Avoidance
The procedure described here involves training an animal to make steady contact with a reward spout in order to receive food or water and then pairing a stimulus with mild electric shock delivered through the spout. The animal quickly learns to avoid the shock by breaking contact with the spout whenever it detects the stimulus. The breaking of contact with the spout is then used to indicate tha...
متن کاملConditioned Disgust, but Not Conditioned Taste Avoidance, May Reflect Conditioned Nausea in Rats
Parker and her colleagues begin their chapter with a fundamental question, i.e., what is the nature of aversion learning. Specifically, they describe the early work of Garcia and his colleagues who interpreted the avoidance of taste associated with various toxic treatments to be a function of conditioned nausea or conditioned disgust. According to this interpretation, the association between th...
متن کاملActive Avoidance: Neural Mechanisms and Attenuation of Pavlovian Conditioned Responding.
Patients with anxiety disorders often experience a relapse in symptoms after exposure therapy. Similarly, threat responses acquired during Pavlovian threat conditioning often return after extinction learning. Accordingly, there is a need for alternative methods to persistently reduce threat responding. Studies in rodents have suggested that exercising behavioral control over an aversive stimulu...
متن کاملCentral administration of ghrelin induces conditioned avoidance in rodents
Feelings of hunger carry a negative-valence (emotion) signal that appears to be conveyed through agouti-related peptide (AgRP) neurons in the hypothalamic arcuate nucleus. The circulating hunger hormone, ghrelin, activates these neurons although it remains unclear whether it also carries a negative-valence signal. Given that ghrelin also activates pathways in the midbrain that are important for...
متن کاملA confounding of conditioned suppression in passive avoidance: ECS effects
In the one-trial passive avoidance paradigm punishment of a highly probable response results in decreased rates and increased latencies of response. Presumably, Sa have learned to avoid the noxious stimulation by not responding. However, decreased response rates may be produced by an alternative procedure-conditioned suppression-where a freezing response conditioned to the situational cues comp...
