Magnetic field conditioned taste aversion in rats.
Conditioned taste aversion is a common classic conditioning procedure used to identify noxious stimuli. When a rat is given a taste solution, the conditioned stimulus (CS), followed by an unpleasant experience, the unconditioned stimulus (US), the rat will avoid consumption of the CS in future presentations. These experiments use the taste aversion procedure to examine the effect of exposure to...
متن کاملKetamine blocks a conditioned taste aversion (CTA) in neonatal rats.
These experiments explored the effects of glutamate, N-methyl-D-aspartate (NMDA) receptor blockade on the formation, retention, and expression of conditioned taste aversion (CTA) in young rats. Previous data from our laboratory suggested that ketamine administration potentiates a CTA in E18 rat fetuses. The current studies investigated this phenomenon in neonates. High-pressure liquid chromatog...
متن کاملLatent inhibition of a conditioned taste aversion in fetal rats.
The etiology of schizophrenia's cognitive symptoms may have its basis in prenatal alterations of glutamate N-methyl-D-aspartate (NMDA) receptor functioning. Therefore, the current study investigated the effects of ketamine (an NMDA receptor blocking drug) on both a conditioned taste aversion (CTA) and latent inhibition (LI; a model of attentional capacity) in rat fetuses. We first sought to det...
متن کاملElectrophysiological analysis of conditioned taste aversion in rats.
The memory mechanisms of conditioned taste aversion (CTA) were examined using electrophysiological methods. Presentation of the aversive taste to CTA trained animals inhibited unit activity in gustatory cortex, amygdala and ventromedial hypothalamus and caused delayed excitation of neurons in lateral hypothalamus. Lick-triggered rewarding stimulation of medial forebrain bundle substituted the t...
متن کاملStimulus generalization of conditioned taste aversion in rats.
Relatively little information is available regarding the intradimensional stimulus generalization of conditioned taste aversion (CTA). Experiment 1 employed a between-groups generalization test to examine the extent to which conditioned flavor aversion to one sucrose solution generalized to other concentrations of sucrose in adult rats. Evidence of a gradient of aversion was obtained. Because g...
