几条证据表明，复杂的气味刺激被解析成单独的数据流在肾小球的嗅球，产生一个组合的“odotopic地图”。然而，这种模式似乎并没有保持在梨状皮质，刺激似乎是在一个分布式的方式编码。嗅前核（AON）是这两个结构之间的中间和间接联系，也为嗅觉信息的大脑半球间传递提供了途径。本研究探讨潜在的编码策略所使用的AON。大鼠暴露于己酸，丁酸，柠檬烯，或净化空气和Fos免疫标记细胞的空间分布进行了定量。AON的两个主要亚区表现出不同的结果。不同的气味特异性的空间活动模式，观察到在部外，这表明它采用了类似于嗅球的气味表示的地形策略。一个空间分布的模式，似乎并不依赖于气味的身份被观察到在部principalis，这表明它采用了分布式表示的气味更相似的梨状皮质。
Several lines of evidence indicate that complex odorant stimuli are parsed into separate data streams in the glomeruli of the olfactory bulb, yielding a combinatorial “odotopic map.” However, this pattern does not appear to be maintained in the piriform cortex, where stimuli appear to be coded in a distributed fashion. The anterior olfactory nucleus (AON) is intermediate and reciprocally interconnected between these two structures, and also provides a route for the interhemispheric transfer of olfactory information. The present study examined potential coding strategies used by the AON. Rats were exposed to either caproic acid, butyric acid, limonene, or purified air and the spatial distribution of Fos-immunolabeled cells was quantified. The two major subregions of the AON exhibited different results. Distinct odor-specific spatial patterns of activity were observed in pars externa, suggesting that it employs a topographic strategy for odor representation similar to the olfactory bulb. A spatially distributed pattern that did not appear to depend on odor identity was observed in pars principalis, suggesting that it employs a distributed representation of odors more similar to that seen in the piriform cortex.
