Phenylthiocarbamide produces conditioned taste aversions in mice.
Previous work has demonstrated that SWR/J (SW) mice avoid phenylthiocarbamide (PTC) to a greater degree than C3HeB/FeJ mice in 48 h, two-bottle preference tests given in ascending series. The authors hypothesized, based also on previous work, that SW mice might form a conditioned taste aversion over time due to the toxic properties of PTC. We directly tested this hypothesis by attempting to con...
متن کاملPrevalence and Genetic Analysis of Bitter Taste Perception for Phenylthiocarbamide (PTC) Among Some Muslim Populations of Uttar Pradesh, India
BACKGROUND The ability to taste Phenylthiocarbamide (PTC), a bitter organic compound, described as a bimodal autosomal trait is widely used to know the heritable trait in both genetic and anthropological studies. The present study was carried out to analyze the prevalence of PTC taste sensitivity and to determine the gene frequencies among some Muslim populations of Uttar Pradesh, India. This s...

متن کاملThe relationship between taste sensitivity to phenylthiocarbamide and anhedonia.
It has been proposed that taste sensitivity to bitter compounds such as, phenylthiocarbamide (PTC) and 6-n-propylthiouracil (PROP), represents a genetic marker for an increased vulnerability to depressive illness. Previous explorations of this idea have proven equivocal. This study refines and further explores this idea by focusing specifically on anhedonia (diminished hedonic capacity), a key ...
متن کاملPossible relationship between phenylthiocarbamide taste sensitivity and epilepsy.
The study was based on the data of a sample of 400 epileptic patients (200 idiopathic and 200 symptomatic) and 100 normal healthy individuals serving as controls. The PTC threshold distribution was bimodal. The number of non-tasters among idiopathic epileptics (35.5%) and symptomatic epileptics (32.5%) was significantly higher than controls (20%). The relative incidence of non-tasters in idiopa...
