Naive and pretrained rats were trained in two active avoidance paradigms using a pole-climbing box and in a single-trial passive avoidance task using a T-maze. They were then subjected to amnestic treatments with electroshock, leptazol, pentobarbitone, or ether anesthesia. Single retention tests were given at 20-24, 44-48, or 68-96 h posttreatment.(More)
HYPOTHESIS Cone-beam computed tomography (CT) is proving useful in various operative settings. We hypothesize that it has great potential as an intraoperative assessment tool for ossicular prosthesis positioning. BACKGROUND Results from prosthetic ossiculoplasty are frequently disappointing. Undetected intraoperative displacement of the prosthesis may be(More)
Albino Wistar rats of both sexes were given a conditioned taste aversion training (CTA). Saccharin was used as the conditional stimulus (CS) and apomorphine-induced illness as the unconditional stimulus (US) on day 4. Amnestic treatment with electroconvulsive shock (ECS) or nitrogen anoxia were given to the rats at various points within the 180-min long(More)
