Although there is behavioral evidence that rat pups respond to odors, the physiological basis of the response is unclear. In the present study, eight different odors were presented to 44 anesthetized rat pups between the ages of 0 and 20 days, and recordings of electrical activity were made from the olfactory bulb. The major finding was that, contrary to earlier neurophysiological findings, even on the first day of life--when spontaneous electrical activity is minimal--evoked potentials, in the form of synchronized waveforms two to four times the amplitude of the background level of spontaneous activity, can be recorded to a variety of odor stimuli.
尽管有行为学证据表明幼鼠对气味有反应，但这种反应的生理基础尚不清楚。在本研究中，将八种不同的气味呈现给44只年龄在0至20天之间的麻醉幼鼠，并从嗅球记录电活动。主要发现是，与早期神经生理学研究结果相反，即使在出生第一天——此时自发电活动最少——对各种气味刺激也能记录到诱发电位，其形式为同步波形，幅度是自发活动背景水平的两到四倍。
