Effects of l-glutamic acid diethyl ester on discrimination learning in rats.
The acquisition of a visuo-tactile simultaneous discrimination task for food reward was evaluated in male albino rats given 0, 120, 240 and 360 mg/kg of l-glutamic acid diethyl ester, an antagonist of quisqualate and kainate receptors. There was an increase in the number of trials to reach the criterion and in the number of errors at the two highest doses of l-glutamic acid diethyl ester in comparison to the two lowest doses. These results indicate a possible role for non-NMDA amino acid receptors in discrimination learning.
