Effects of MDA on classical conditioning of the rabbit nictitating membrane response.
Pharmacology, biochemistry, and behavior May 1991 K Kirkpatrick-Steger, S Vander Linden, I Gormezano
In Experiment 1, classical conditioning of the rabbit's nictitating membrane response (NMR) was accomplished by pairing tone and light conditioned stimuli (CSs) with a shock unconditioned stimulus (UCS). MDA impaired the acquisition of conditioned responses (CR) to a tone-CS, while significantly enhancing CR acquisition to a light-CS. Experiment 2, employing explicitly unpaired CS, UCS...
