Behavioral tagging of extinction learning.
Extinction of contextual fear in rats is enhanced by exposure to a novel environment at 1-2 h before or 1 h after extinction training. This effect is antagonized by administration of protein synthesis inhibitors anisomycin and rapamycin into the hippocampus, but not into the amygdala, immediately after either novelty or extinction training, as well as by the gene expression blocker 5,6-dichloro...
متن کاملBehavioral tagging and the penumbra of learning
In noisy, dynamic environments, organisms must distinguish genuine change (e.g., the movement of prey) from noise (e.g., the rustling of leaves). Expectations should be updated only when the organism believes genuine change has occurred. Although individual variables can be highly unreliable, organisms can take advantage of the fact that changes tend to be correlated (e.g., movement of prey wil...
متن کاملBehavioral and neural bases of extinction learning in Hermissenda
Extinction of classical conditioning is thought to produce new learning that masks or interferes with the original memory. However, research in the nudibranch Hermissenda crassicornis (H.c.) has challenged this view, and instead suggested that extinction erased the original associative memory. We have re-examined extinction in H.c. to test whether extinguished associative memories can be detect...
متن کاملEffects of quinpirole on behavioral extinction.
Behavioral effects of quinpirole (QNP), a dopamine D(2) receptor agonist, suggest it impacts neural mechanisms mediating goal-directed behaviors, as well as behavioral extinction following removal of a primary reinforcer. The present study investigated the effect of QNP on behavioral extinction following the omission of contingent reinforcement, and whether this effect is related to acquisition...
متن کاملBehavioral and Neural Analysis of Extinction
The neural mechanisms by which fear is inhibited are poorly understood at the present time. Behaviorally, a conditioned fear response may be reduced in intensity through a number of means. Among the simplest of these is extinction, a form of learning characterized by a decrease in the amplitude and frequency of a conditioned response when the conditioned stimulus that elicits it is repeatedly n...
