The interaction of psychomotor stimulants and sedative hypnotics in the conditioned taste aversion paradigm
… of drugs as reflected in two variants of the Conditioned Taste Aversion (CTA) paradigm. Experiment 1 examined the potential for cocaine and ethanol to interact pharmacologically in the pretreatment CTA procedure. These results revealed that while cocaine and ethanol may interact …

Effects of diversity training and a retention interval on neophobia and conditioned taste aversion
… for neophobia and training and testing for conditioned taste aversion to saline. At the one-day interval, preexposures to saline, hydrochloric, or multiple flavors attenuated neophobia to saline while only preexposures to saline attenuated the conditioned aversion to saline. At the 28-day …

A Behavioral and Anatomical Analysis of Conditioned Taste Aversion in C57BL/6J and DBA/2J Mice
<p>Conditioned taste aversion (CTA) has been commonly used as a model of learning and memory. Traditionally, CTA approaches have used a paradigm that follows the model of classical conditioning. This involves presentation of a novel tastant, such as sucrose (conditioned stimulus, CS), followed by …

Increase of glucocorticoids is not required for the acquisition, but hinders the extinction, of lithium-induced conditioned taste aversion
Lithium chloride at doses adequate to induce conditioned taste aversion (CTA) causes c-Fos expression in the paraventricular nucleus and increases the plasma level of corticosterone with activation of the hypothalamic–pituitary–adrenal axis. This study was examined to define the role of …

Circadian activation of the hypothalamic-pituitary-adrenal axis may affect central, but not peripheral, effect of lithium in conditioned taste aversion learning in rats
… (HPA) axis has been implicated in conditioned taste aversion (CTA) learning induced by lithium chloride. This study investigated if circadian activation of the HPA axis affects the lithium-induced CTA formation. The pairing of conditioned stimulus (sucrose) and unconditioned …

Effects of Alterations in Monoamine Levels on Conditioned Taste Aversions in the Rat.
… serotonin in mediating LiCl-based conditioned taste aversions. Previous research has indicated that reductions in forebrain serotonin levels produce a more potent conditioned taste aversion in the rat and that pretreatment with the serotonin precursor, 5-hydroxytryptophan, will …

Effects of pre-exposure concentration in neophobia and taste aversion learning
… water or 2% saline prior to testing for conditioned taste aversion or neophobia. Pre-exposure to high saccharin concentration attenuated neophobia and taste aversion to high and low concentrations. Pre-exposure to the low concentration attenuated neophobia to both concentrations but …

Arc expression in the parabrachial nucleus following taste stimulation
… to study the complexities of the mammalian taste system; however molecular mechanisms of taste processing in the early structures of the central taste pathway remain unclear. More recently the Arc catFISH (cellular compartment analysis of temporal activity by fluorescent in situ …

Taste Learning in Insular Cortex: Plasticity Is Influenced by Experience Type
… been studied as the main cortical area encoding taste stimuli and likely integrates sensory, visceral, and emotional information to guide taste-related behaviors. However, our understanding of cortical taste coding on a single-cell level has only become clear in recent years. The anatomical …

Galanin-like peptide: a molecular link between energy homeostasis and reproduction
… activity and elicits the formation of a conditioned taste aversion, which raises the possibility that GALP's anorectic effect does not reflect a homeostatic regulation of energy balance. I also observed that ICV GALP treatment robustly stimulates luteinizing hormone (LH) and testosterone …

Prenatal Intravenous Nicotine Exposure: Increased Motivation For Methamphetamine Self-Administration, Altered Methamphetamine-Induced Locomotor Activity and Brain-Derived Neurotrophic Factor Protein Levels In Adult Rats
… Therefore, the present study utilized the conditioned taste aversion procedure (CTA) to investigate the aversive effects of the highly addictive drug methamphetamine (METH). Specifically, the experiment investigated the impact of US-preexposures on METH-induced CTA, in periadolescent (PND …

The Effect of Us-Preexposure On Meth-Induced Cta In Periadolescent and Young Adult Rats

A neural and behavioural investigation of aberrant feeding in animal models of autism spectrum disorder
… to VPA exhibit impaired acquisition of the conditioned taste aversion (CTA), a protective learning mechanism against ingestion of foods inducing nausea/malaise. Feeding issues in ASD, such as pica, may reflect disruptions in aversion-based learning. Additionally, OT has been implicated in …

Anthraquinone Corn Seed Treatment (Avitec™) As A Feeding Repellent for Ring-Necked Pheasants (Phasianus colchicus) on Newly Planted Corn in Eastern South Dakota
… post-ingestional irritant that produces a conditioned taste aversion when the bird experiences illness after consuming the treated kernel and associates the illness with the food (Avery 2003). AvitecTM is a 95% anthraquinone repellent that has been approved for emergency use in Wisconsin, …

Interrogation of the neural mechanisms by which male and female rats assess aversive and mixed valence stimuli in learning and performing a task
… assessment of affective valence. In contrast, conditioned taste aversion (CTA) is a behavioral paradigm in which a palatable substance is paired with an aversive visceral experience, generally an injection of a nausea-inducing agent such as lithium chloride (LiCl), to produce aversion to the …

Neuromolecular basis of anomalous feeding behaviour in the valproate rat model of autism
… foods, i.e., it facilitates the development of a conditioned taste aversion (CTA). Therefore, the goal of the Specific Aim 4, was to assess whether VPA animals display atypical taste aversion acquisition. It was found that VPAs failed to develop aversion to a standard dose of LiCl that induces a …
