躯体标记假说为决策以及情绪对决策的影响提供了一个系统水平的神经解剖学和认知框架。这一假说的关键思想是，决策是一个受生物调节过程中出现的标记信号影响的过程，包括那些以情绪和感觉表达自己的过程。这种影响可以在多个操作层面上发生，其中一些是有意识的，有些是无意识的。在这里，我们回顾了证实这一假说的各种预测的研究。眼眶前额叶皮质是神经系统中的一个重要结构，为决策服务。决策不是由眶前叶皮质单独调节的，而是由包括其他皮质和皮质下成分的大规模系统产生的。这些结构包括杏仁核、躯体感觉/岛叶皮质和外周神经系统。这里我们只关注眼眶额叶皮质在决策和情绪处理中的作用，以及情绪、决策和额叶其他认知功能之间的关系。即工作记忆。
The somatic marker hypothesis provides a systems-level neuroanatomical and cognitive framework for decision making and the influence on it by emotion. The key idea of this hypothesis is that decision making is a process that is influenced by marker signals that arise in bioregulatory processes, including those that express themselves in emotions and feelings. This influence can occur at multiple levels of operation, some of which occur consciously and some of which occur non-consciously. Here we review studies that confirm various predictions from the hypothesis. The orbitofrontal cortex represents one critical structure in a neural system subserving decision making. Decision making is not mediated by the orbitofrontal cortex alone, hut arises from large-scale systems that include other cortical and subcortical components. Such structures include the amygdala, the somatosensory/insular cortices and the peripheral nervous system. Here we focus only on the role of the orbitofrontal cortex in decision making and emotional processing, and the relationship between emotion, decision making and other cognitive functions of the frontal lobe. namely working memory.
