Rats exposed to sweetened water with glucose show binge drinking response whereas rats exposed to sweetened water with sucralose do not show binge drinking response. This result is similar although it modified the sweetener presentation sequence. The objective of this work was to replicate the obtained results in rats with other species of rodent: Octodon-Degus, who has peculiar feeding characteristics like they drink few water and they do not metabolize properly the sugars. Results showed the subjects emit binge drinking response of sweetened water with glucose whereas they showed an increase of sweetened water with sucralose only the first day of access to the sweetener without calories. These results confirm that great quantity of sweetened solution intake can showed in another species of rodent experimentally

Palabras clave : Intake; sweetened solutions; glucose; sucralose; octodon-degusoperant variability; induced variability; extinction; behavioral history; positive reinforcement; animal behavi or; rats.
