Abstract

The conditioned place preference (CPP) paradigm is commonly used to investigate the motivational properties of drugs of abuse. Cues in the environment may become paired with these motivational properties and later result in drug seeking. Because many of these alcohol-paired cues are visual, Japanese quail may be a beneficial model to examine visual cue-induced alcohol seeking behavior. The aim of the present study was to examine the motivational properties of ethanol using a visual CPP model. During CPP, quail were given an initial preference test to determine their initially preferred chamber, during which time they could explore the entire chamber for 15 min. Following the initial preference test, quail were gavaged with their assigned treatment (water or 0.75 or 2.0 g/kg of ethanol) and were confined to their initially least preferred chamber every other conditioning day for 30 min. On alternate days, they were gavaged with water and confined to the preferred chamber for 30 min. After the 8th day of conditioning, a final preference test was given. Locomotor activity was also measured during conditioning. The findings indicated that quail that received the 0.75 g/kg ethanol developed a place preference to the ethanol-paired chamber, and that quail treated with 2 g/kg ethanol developed a place aversion to the ethanol-paired chamber. Additionally, locomotor activity was reduced in quail that received the high dose of ethanol.
