Over the last ten years, methods of cerebral imaging have revolutionized our knowledge of cognitive processes in humans. An impressive number of papers dealing with cerebral imaging for olfaction have been published to date. Whereas the early works revealed those structures participating in the processing of odours presented passively to subjects, researchers later recorded brain activity when subjects performed specific olfactory tasks based on memory, emotion and identification. From these results, we suggest that there is a dissociation of olfactory processes, with involvement of the right hemisphere in memory processes and the left hemisphere in emotional processes. The review concludes with a summary of how these lateralized processes are consistent with the gestalt-nature of our olfactory perception.
在过去十年中，脑成像方法彻底改变了我们对人类认知过程的认识。迄今为止，已经发表了大量关于嗅觉脑成像的论文。早期的研究揭示了参与被动呈现给受试者的气味处理的那些结构，后来研究人员记录了受试者在执行基于记忆、情感和识别的特定嗅觉任务时的大脑活动。从这些结果来看，我们认为嗅觉过程存在分离，右半球参与记忆过程，左半球参与情感过程。综述最后总结了这些偏侧化过程如何与我们嗅觉感知的格式塔性质相一致。
