NEURAL CORRELATES OF MEMORY FOR ODOR DETECTION CONDITIONING IN ADULT-RATS

Adult male Wistar rats were trained in a simple odor detection task, w ith peppermint odor serving as either an S+, S- or as a randomly prese nted odor. Twenty-four hours after the last training session, rats wer e injected with [C-14]2-deoxyglucose and exposed to the odor. Mean rel ative 2-deoxyglucose uptake to the odor was enhanced in the pars dorsa lis of the anterior olfactory nucleus of S+ and S- trained rats compar ed to controls. In contrast, no differences in uptake were detected in either odor-specific focal regions of the olfactory bulb glomerular l ayer, the pyriform cortex, or the hippocampus.
