Acquisition and extinction of conditioned nicotine analgesic tolerance

[The influence of sex and menstrual cycle on conditioned acquisition and extinction: Event-related potential research].

Previous studies have indicated phase-related differences in conditioned acquisition and extinction. In recent years, many researchers used event-related potential (ERP) technology to assess the extent of the acquisition and extinction. Therefore, this study was aimed to assess the sex- and menstrual cycle-dependent effects on the conditioned acquisition and extinction using ERP technology. Thi...

Optimising Extinction of Conditioned Disgust

Maladaptive disgust responses are tenacious and resistant to exposure-based interventions. In a similar vein, laboratory studies have shown that conditioned disgust is relatively insensitive to Conditioned Stimulus (CS)-only extinction procedures. The relatively strong resistance to extinction might be explained by disgust's adaptive function to motivate avoidance from contamination threats (pa...

Context specificity of both acquisition and extinction of a Pavlovian conditioned response.

It is widely held that the extinction of a conditioned response is more context specific than its initial acquisition. One proposed explanation is that context serves to disambiguate the meaning of a stimulus. Using a procedure that equated the learning histories of the contexts, we show that the memory of an appetitive Pavlovian association can be highly context specific despite being unambigu...

Plastic Synaptic Networks of the Amygdala for the Acquisition, Expression, and Extinction of Conditioned Fear

Effects of midazolam on acquisition and extinction of conditioned taste aversion memory in rats.

Some intravenous anesthetic agents such as midazolam are known to induce anterograde and retrograde amnesia. We analyzed the effect of midazolam by the conditioned taste aversion (CTA) acquisition and retention. After the rats were offered 0.1% sodium saccharin (Sac) as conditioned stimulus (CS), an intraperitoneal (i.p.) injection of several concentrations (5-30mg/kg) of midazolam was followed...
