Reward devaluation disrupts latent inhibition in fear conditioning.
Three experiments explored the link between reward shifts and latent inhibition (LI). Using consummatory procedures, rewards were either downshifted from 32% to 4% sucrose (Experiments 1-2), or upshifted from 4% to 32% sucrose (Experiment 3). In both cases, appropriate unshifted controls were also included. LI was implemented in terms of fear conditioning involving a single tone-shock pairing a...
متن کاملPrior fear conditioning and reward learning interact in fear and reward networks
The ability to flexibly adapt responses to changes in the environment is important for survival. Previous research in humans separately examined the mechanisms underlying acquisition and extinction of aversive and appetitive conditioned responses. It is yet unclear how aversive and appetitive learning interact on a neural level during counterconditioning in humans. This functional magnetic reso...
متن کاملBlockade of NMDA receptors in the amygdala prevents latent inhibition of fear-conditioning.
The association between a conditioned stimulus (CS) and an unconditioned stimulus (US) in fear-conditioning depends on N-methyl-D-aspartate (NMDA) receptors in the basolateral amygdala complex (BLA). Latent inhibition (LI) is the retardation in learning due to nonreinforced presentation of the prospective CS before conditioning. Disruption of LI in rats is an animal model of schizophrenia, refl...
متن کاملPrior cocaine exposure disrupts extinction of fear conditioning.
Psychostimulant exposure has been shown to cause molecular and cellular changes in prefrontal cortex. It has been hypothesized that these drug-induced changes might affect the operation of prefrontal-limbic circuits, disrupting their normal role in controlling behavior and thereby leading to compulsive drug-seeking. To test this hypothesis, we tested cocaine-treated rats in a fear conditioning,...
متن کاملFear Conditioning Effects on Sensitivity to Drug Reward
This study examined mechanisms of expression and extinction of fear conditioning, as an animal model of post-traumatic stress disorder, and also fear conditioning effects on drug reward. C57BL/6 mice were fear conditioned via repeated exposure to aversive stimuli (footshock co-terminating with a tone) or a sham procedure. After training, mice demonstrated freezing behaviors over 80% of the time...
