Increased liking for a solution is not necessary for the attenuation of neophobia in rats
(American Psychological Association, 2010-06)
Recent evidence suggests that liking and wanting of food rewards can be experimentally dissociated (e.g., Berridge, 1996); this dissociation extends to attenuated neophobia in the present study. Rats tend to eat less of ...
Role of the Gustatory Thalamus in Taste Learning
(Elsevier Inc., 2013-08)
The present study re-examined the involvement of the gustatory thalamus (GT) in the acquisition of drug- and toxin-induced conditioned taste aversions (CTAs) using a standardized procedure involving 15-min taste trials in ...
Role of the Insular Cortex in Morphine-Induced Conditioned Taste Avoidance
The present study investigated the role of the insular cortex (IC) in morphine-induced conditioned taste avoidance. The results of Experiment 1 revealed that IC lesions impaired taste neophobia, retarded acquisition of ...
Reduced palatability in drug-induced taste aversion: II. Aversive and rewarding unconditioned stimuli.
(American Psychological Association, 2012-06)
Drugs of abuse are known to reduce intake of a taste conditioned stimulus (CS), a behavioral response sometimes seen as paradoxical because the same drugs also serve as rewards in other behavioral procedures. In the ...
Inhibiting gustatory thalamus or medial amygdala has opposing effects on taste neophobia
Taste neophobia is a feeding system defense mechanism that limits consumption of an unknown, and therefore potentially dangerous, edible until the post-ingestive consequences are experienced. We found that transient ...
