Natural odors, generally composed of many monomolecular components, are analyzed by peripheral receptors into component features and translated into spatiotemporal patterns of neural activity in the olfactory bulb. Here, we will discuss the role of the olfactory cortex in the recognition, separation and completion of those odor-evoked patterns, and how these processes contribute to odor perception. Recent findings regarding the neural architecture, physiology, and plasticity of the olfactory cortex, principally the piriform cortex, will be described in the context of how this paleocortical structure creates odor objects.
天然气味通常由许多单分子成分组成，通过外周受体将其分析成成分特征，并转化为嗅球中神经活动的时空模式。在这里，我们将讨论嗅皮层在识别、分离和完成这些气味诱发模式中的作用，以及这些过程如何有助于气味感知。本文将主要描述梨状皮层等古皮层结构如何创建气味物体，讨论嗅皮层的神经结构、生理学和可塑性的最新发现。
