Mildly thirsty rabbits were classically conditioned by reinforcement with water to give a discriminative licking response to the presentation of odors. The jaw movement component of the licking conditioned response (JM CR) was elicited only by the reinforced odor; an increase in the relative frequency of sniffing (RR CR) occurred to both reinforced (CS+) and nonreinforced (CS-) odors. Oscillatory electroencephalographic bursts of high-frequency (40-80 Hz) potentials were recorded epidurally from the lateral olfactory bulb with 64-electrode arrays (8 X 8, 3.5 X 3.5 mm) chronically implanted. Emphasis was on comparing bursts during odor presentation with bursts preceding odor arrival on each trial. A "detection" burst was characterized as occurring immediately after odor arrival and before the sniff response. "Discrimination" bursts occurred during the RR CR and before the JM CR onset. Significant air-odor burst differences (together with sniffing) occurred through up to six sessions for both CS+ and CS- odors for "discrimination" bursts but not for "detection" bursts.
轻度口渴的兔子通过用水强化进行经典条件反射，以对气味的呈现做出辨别性舔舐反应。舔舐条件反应（JM CR）的下颌运动成分仅由强化气味引发；对强化（CS +）和非强化（CS -）气味都出现了嗅探相对频率的增加（RR CR）。使用长期植入的64电极阵列（8×8，3.5×3.5毫米）从外侧嗅球硬膜外记录高频（40 - 80赫兹）电位的振荡脑电图爆发。重点是比较每次试验中气味呈现期间的爆发与气味到达之前的爆发。“检测”爆发的特征是在气味到达后且在嗅探反应之前立即发生。“辨别”爆发发生在RR CR期间且在JM CR开始之前。对于CS +和CS -气味，“辨别”爆发在多达六个实验阶段中都出现了显著的空气 - 气味爆发差异（与嗅探一起），但“检测”爆发没有。
