AIMS To characterize the relationship between the sucrose- and ethanol-reinforced behaviour in Wistar rats. METHODS Subjects (n = 31) were trained to lever press for 8% (v/v) ethanol in an operant procedure where increasing concentrations of ethanol were introduced in the presence of 8% (w/v) sucrose. The sucrose concentration was subsequently decreased from 8 to 0%. Subjects were allowed to ...

Background: The intermittent access 2-bottle choice (IA2BC) and drinking in the dark (DID) models were developed for studying rodent binge-like consumption. Traditionally, IA2BC was used with rats and DID with mice. Recently, IA2BC was adapted to study mouse ethanol consumption. However, it is unknown whether DID is suitable for rats or if one rat model is more advantageous than another for stu...

Strain differences between naive, sucrose- and ethanol-exposed alcohol-preferring (P) and alcohol-nonpreferring (NP) rats were investigated in their consumption of ethanol, sucrose, and NaCl; chorda tympani (CT) nerve responses to sweet and salty stimuli; and gene expression in the anterior tongue of T1R3 and TRPV1/TRPV1t. Preference for 5% ethanol and 10% sucrose, CT responses to sweet stimuli...
