During postnatal days 1-18, pups were simultaneously exposed to an odor and reinforcing tactile stimulation similar to that normally received from the dam. Control pups received only the odor, only the stimulation, or neither of these stimuli. On postnatal day 19, pups that had previously received simultaneous odor and tactile stimulation displayed both a behavioral odor preference and an enhanced 2-deoxyglucose uptake in specific olfactory bulb glomeruli to subsequent presentation of that odor. These results suggest that early olfactory learning enhances the neural response to odors that have acquired attractive value.
在出生后的第1至18天，幼崽同时接触一种气味和类似于通常从母鼠那里获得的强化触觉刺激。对照幼崽只接受气味、只接受刺激或两者都不接受。在出生后的第19天，先前同时接受气味和触觉刺激的幼崽对随后呈现的那种气味表现出行为上的气味偏好以及特定嗅球小球中2-脱氧葡萄糖摄取增加。这些结果表明，早期嗅觉学习增强了对已获得吸引力价值的气味的神经反应。
