The Effect Of Early Handling On The Sexually Dimorphic Rate Of Extinction Of A Conditioned Taste Aversion In Rats, Rebecca Lee Yoder

Male rats have been found to extinguish a conditioned taste aversion slower than females. It has also been found that female rats that have been "handled" (i.e., exposed to daily brief isolation from siblings and mother) during the preweaning period extinguish a taste aversion faster than nonhandled females. The present study sought to combine and extend these findings by testing handled and nonhandled females and males in a conditioned taste aversion under the methodological conditions used in the sex difference research.

Exteroceptive Influence On A Marihuana Induced Conditioned Taste Aversion, Albert William Greenwood

Forty-five male, Sprague Dawley rats were used to determine if external stimuli could influence the length of a conditioned taste aversion. Animals were given a novel taste (sucrose), and then injected with one of three different substances, marihuana, LiCI, or saline. The animals were then placed into either a stimulation condition, a non-stimulation condition, or returned to the home cage. The stimulation condition contained aversive stimuli in the form of bright, flashing lights and loud noises. The other conditions had no aversive stimulation. It was expected that the animals receiving injections of marihuana would have an increase in their responsiveness …
