Pretest CS Cueing Facilitates the Recovery of Avoidance Behavior Following Visual Cortex Lesions in the Rat

Fritts, Mary E., Asbury, E. Trey, Isaac, Walter L. 15 February 1998 (has links)
Rats were trained on a four-way shuttle box with a compound light-tone conditioned stimulus (CS) until they emitted 7 avoidance responses in 10 trials (7/10) prior to bilateral ablation of the visual cortex or sham surgery. On Day 5 after surgery, rats were cued with either the compound light-tone CS, the light or tone portion of the CS only, or had no exposure to the CS. On Day 10 after surgery, all animals were tested for avoidance retention under the same conditions as preoperative training. The findings indicate that following a lesion, cueing with the light-tone compound CS facilitates performance as does light alone. Cueing to the tone alone has no effect. In sham animals, only cueing with the light-tone CS was effective in enhancing avoidance retention. Results are interpreted as early and modality-specific sensory cueing may facilitate the recovery process.
