来自不同的动物和人类的行为证据表明,嗅觉在解释空间和时间方面的作用可能比迄今为止所想象的要大得多,它可以提取嗅觉信号中固有的时间信息。如果是这样的话,嗅觉系统一定具有神经机制,能够在与许多动物生活的动荡的气味世界相关的间隔中编码时间。我们回顾了动物可以利用有节奏地活跃或“爆发”的嗅觉受体神经元(伯恩斯)群体来提取和编码自然嗅觉信号中固有的时间信息的证据。我们假设伯恩斯代表了一种未知的神经机制,通过这种机制可以精确地测量时间,并且“嗅觉时间”完成了真实嗅觉场景分析的要求。
Behavioral evidence from phylogenetically diverse animals and humans suggests that olfaction could be much more involved in interpreting space and time than heretofore imagined by extracting temporal information inherent in the olfactory signal. If this is the case, the olfactory system must have neural mechanisms capable of encoding time at intervals relevant to the turbulent odor world in which many animals live. We review evidence that animals can use populations of rhythmically active or ‘bursting’ olfactory receptor neurons (bORNs) to extract and encode temporal information inherent in natural olfactory signals. We postulate that bORNs represent an unsuspected neural mechanism through which time can be accurately measured, and that ‘smelling time’ completes the requirements for true olfactory scene analysis.
