Helplessness in hippocampectomized rats: Response perseveration?
In a test for learned helplessness, hippocampectomized rats, cortical controls and unoperated controls were given shock-escape training after being subjected to a series of noncontingent shocks. During these preshock treat!llents, the ~ame amount of gross body activity was elicited in all three groups. Compared to rats that dId not receIve the preshock treatments, all the preshocked animals per...
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 کاملAripiprazole Facilitates Extinction of Conditioned Fear in Adolescent Rats
Anxiety disorders are the most common type of mental disorder during adolescence, which is at least partly due to the resistance to extinction exhibited at this age. The dopaminergic system is known to be dysregulated during adolescence; therefore, we aimed to facilitate extinction in adolescent rats using the dopamine receptor 2 partial agonist aripiprazole (Abilify™), and examine the behavior...
متن کاملEffects of Panax Ginseng root on conditioned avoidance response in rats.
Pole climbing and shuttle box tests were employed to study conditioned avoidance response (CAR) and discrimination behaviour in Wistar male rats given extracts from Panax Ginseng root intraperitonealy. Neutral saponins (GNS), a water soluble fraction (GF4) which does not contain saponins, and a lipid soluble fraction (GNo. 5) inhibited CAR and discrimination ability between 500 Hz sound with el...
متن کاملMuscarinic receptor agonists, like dopamine receptor antagonist antipsychotics, inhibit conditioned avoidance response in rats.
The purpose of our studies was to determine the effects of muscarinic receptor agonists on conditioned avoidance responding in the rat. Rats were trained to avoid or escape an electric shock delivered to the feet in a discrete trial procedure. The muscarinic receptor agonists pilocarpine and [2-ethyl-8-methyl-2,8-diazaspiro(4. 5)decane-1,3-dione] hydrochloride (RS86) and the cholinesterase inhi...
