Using a conditioned taste aversion procedure with rats as the subjects, two experiments examined the effect of presenting a conditioned stimulus (CS saccharin solution) in one context followed by an unconditioned stimulus (US LiCl) in a different context. Experiment 1 showed that animals which ...
For full details, see Supplementary Modeling Note and Supplementary Tables 2 and 3. Below is a brief summary of the model-based analysis including model comparison, peristimulus activity, value coding index, simulated datasets and choice-predictive activity. Model comparison...
Using fear-conditioning model, we have used a 3-s auditory conditioned stimulus (CS) as a stressor and observed fear and stress responses during a specific experimental period regardless of the presence or absence of the CS. Because the CS was extremely short compared with the experimental period...
US: unconditioned stimulus (violet). After experiencing CS and US pairings at a fixed temporal interval over many trials, the animal learns to close its eyelid just before the US is delivered (green). A pause in PC activity (blue) precedes the eyelid closure (target time, gray dashed line...
(e.g., Shemesh et al.2010). But these examples always involve sensing and following a stimulus trail (“responses to stimuli”; “proactively sampling”: Calvo et al.2017; Calvo and Friston2017), which is reactive, not proactive. Rather than reflecting consciousness, it seems that plant ...
(a) there may be an unidentified sexual attraction pheromone that elicits inherent female attraction to spend time near adult male mouse urine; and (b) contact with this sex pheromone may stimulate associative learning of a male's airborne urinary odour as a conditioned stimulus, so that, ...
During subsequent phases, it was shown that previously non-shocked S s buried the flash stimulus only when it was made partially accessible. The results of this four-phase experiment indicate that the defensive-burying response is sensitive to both the modality and accessibility of the aversive ...
