嗅觉感觉神经元检测到的气味信号在嗅球的轴突末端被表示为气味图。在嗅球的二尖瓣/簇状细胞中，气味信息不仅由放电率表示，还由活动的时间模式（相位编码）表示，这用于浓度不变的气味身份编码。二尖瓣/簇状细胞活性还表现出塑性变化，能够以上下文相关的方式有效、稳健地识别气味。
Odor signals that are detected by olfactory sensory neurons are represented as an odor map in their axon terminals in the olfactory bulb. In the mitral/tufted cells of the olfactory bulb, odor information is represented not only by the firing rate, but also by the temporal patterns of activity (phase coding), which is utilized for concentrationinvariant odor identity coding. Mitral/tufted cell activity also shows plastic changes to efficiently and robustly recognize odors in a context-dependent manner.
