Preexposure to salty and sour taste enhances conditioned taste aversion to novel sucrose.
Conditioned taste aversion (CTA) is an intensively studied single-trial learning paradigm whereby animals are trained to avoid a taste that has been paired with malaise. Many factors influence the strength of aversion learning; prominently studied among these is taste novelty-the fact that preexposure to the taste conditioned stimulus (CS) reduces its associability. The effect of exposure to ta...
متن کاملConditioned taste aversion and latent inhibition following extensive taste preexposure in rats with insular cortex lesions.
Lesions of the insular cortex (IC) attenuate acquisition of conditioned taste aversions (CTAs). We have suggested that this impairment is the expected consequence of a failure of IC-lesioned (ICX) rats to recognize unfamiliar taste stimuli as novel. That is, ICX rats treat novel taste stimuli as if they are familiar and as a result show a latent inhibition-like retardation of learning. This acc...
متن کاملConditioned Taste Aversion Learning in Adolescent and Adult Rats
Pharmacology and Cancer Biology at the Duke University Medical Center in Durham, NC. In 2004, Dr. Schramm-Sapyta and her colleagues at Vanderbilt assessed the rewarding effects of cocaine in adolescent and adult rats and noted no distinct differences in the acquisition of cocaine-induced place preferences between the two groups. Given her focus on the balance of the rewarding and aversive effec...
متن کاملAmiloride is an ineffective conditioned stimulus in taste aversion learning.
The present study demonstrated that 100 microM amiloride serves as an ineffective conditioned taste stimulus in a taste aversion paradigm. Even if amiloride has a detectable taste, it's unlikely that its behavioral effects in salt mixture experiments are due to its inherent taste quality.
متن کاملImpaired conditioned taste aversion learning in spinophilin knockout mice.
Plasticity in dendritic spines may underlie learning and memory. Spinophilin, a protein enriched in dendritic spines, has the properties of a scaffolding protein and is believed to regulate actin cytoskeletal dynamics affecting dendritic spine morphology. It also binds protein phosphatase-1 (PP-1), an enzyme that regulates dendritic spine physiology. In this study, we tested the role of spinoph...
