Water-deprived and nondeprived rats were fear conditioned with a discrete tone conditional stimulus (CS) and an aversive footshock unconditional stimulus (US). Twenty-four and 48 hr following conditioning, conditional fear to the tone CS and the cont

The influence of water deprivation on hippocampal long-term potentiation (LTP), theta rhythm, and contextual fear conditioning in rats was examined. In Experiment 1, hippocampal EEG activity and perforant path LTP were assessed in pentobarbital-anest

Massed presentation of unsignaled shock results in less conditional freezing to contextual cues than do distributed presentations. Consistent with an account of the learning deficit based on the perceptual-defensive-recuperative theory, the massed-sh

Previous research has indicated that the competitive N-methyl-D-aspartate (NMDA) antagonist APV (DL-2-amino-5-phosphonovalerate) prevents the Pavlovian conditioning of fear to contextual stimuli when tested 24 hr, but not immediately, after training.

The role of N-methyl-D-aspartate (NMDA) receptors in Pavlovian fear conditioning was examined using the NMDA antagonist DL-2-amino-5-phosphonovaleric acid (APV). Either APV (5 micrograms/rat) or saline was administered before the training phase, the

Learned helplessness theory predicts that animals exposed to inescapable shock acquire an expectancy of response-reinforcer independence, which proactively interferes with learning of response-reinforcer dependence. The theory also predicts that this

In experiments 1 and 2, we examined the learned helplessness and immunization effects using a test in which appetitive responding was extinguished by delivering noncontingent reinforcers. Contrary to learned helplessness theory, "immunized" animals s
