在一系列旨在研究情绪和感觉的神经基础的 [O-15]PET 实验中，41 名正常受试者回忆并重新经历了以悲伤、快乐、愤怒或恐惧为标志的个人生活片段。我们测试了这样的假设：感受情绪的过程需要大脑区域的参与，例如体感皮层和上脑干核团，这些区域参与内部有机体状态的映射和/或调节。这些区域确实参与其中，强调了情绪与体内平衡之间的密切关系。研究结果还支持了这样一种观点，即感受情绪的主观过程部分基于动态神经图，它代表了有机体不断变化的内部状态的几个方面。
In a series of [O-15]PET experiments aimed at investigating the neural basis of emotion and feeling, 41 normal subjects recalled and re-experienced personal life episodes marked by sadness, happiness, anger or fear. We tested the hypothesis that the process of feeling emotions requires the participation of brain regions, such as the somatosensory cortices and the upper brainstem nuclei, that are involved in the mapping and/or regulation of internal organism states. Such areas were indeed engaged, underscoring the close relationship between emotion and homeostasis. The findings also lend support to the idea that the subjective process of feeling emotions is partly grounded in dynamic neural maps, which represent several aspects of the organism's continuously changing internal state.
