Rats' brains may remember odors they were exposed to while deeply anesthetized, suggests research. In the study, rats were exposed to a specific odor while under general anesthesia. Examination of the brain tissue after they had recovered from anesthesia revealed evidence of cellular imprinting, even though the rats behaved as if they had never encountered the odor before.
