目前还不清楚大脑是如何代表外部客观感觉事件以及我们对它们的内部主观印象的。复杂场景和基本口味引发的群体水平活动的代表性映射发现了一种支持从愉快到不愉快效价连续轴的神经代码。这种价代码与低层次的物理属性和高层次的对象属性不同。虽然腹侧颞叶和前岛叶皮质支持视觉和味觉特异性的价代码,内侧和外侧眶额皮质(OFC),保持独立于感觉起源的价代码。此外,只有OFC代码可以对参与者的情感体验进行分类。整个效价谱被表示为区域神经活动中的集体模式,作为感官特异性和抽象代码,从而可以客观地量化情感的主观质量。
It remains unclear how the brain represents external objective sensory events alongside our internal subjective impressions of them—affect. Representational mapping of population level activity evoked by complex scenes and basic tastes uncovered a neural code supporting a continuous axis of pleasant-to-unpleasant valence. This valence code was distinct from low-level physical and high-level object properties. While ventral temporal and anterior insular cortices supported valence codes specific to vision and taste, both the medial and lateral orbitofrontal cortices (OFC), maintained a valence code independent of sensory origin. Further only the OFC code could classify experienced affect across participants. The entire valence spectrum is represented as a collective pattern in regional neural activity as sensory-specific and abstract codes, whereby the subjective quality of affect can be objectively quantified across stimuli, modalities, and people.
