The bipolar valence-arousal model is assumed by many to be an underlying structure of conscious experience of core affect and emotion. In this work, we compare three versions of the bipolar valence-arousal model at the neural domain, using functional magnetic resonance imaging (fMRI). Specifically, we systematically contrast three models of arousal: model 1-'arousal as a separate quale from valence', model 2-'arousal as intensity of bipolar valence' and model 3-'arousal as a linear combination of unipolar pleasant and unpleasant'. Using parametric modulation analysis, we estimated the ability of each model to predict activation in arousal-related brain regions, in response to affective stimuli. The results suggest that arousal is not separable from valence in its ability to predict arousal-related neural activity. The relevance of the results to the theory of conscious affect is discussed.

比较人脑中的三种唤醒模式。

许多人认为双极性价-兴奋模型是核心情感和情感的有意识体验的基础结构。在这项工作中，我们使用功能磁共振成像（fMRI）在神经域比较了三种版本的双极化合价-兴奋模型。具体而言，我们系统地对比了三种唤醒模型：模型1-'芳香作为价数的一个独立质'，模型2-'芳香作为双极价的强度'和模型3-'芳香作为单极愉悦和不愉快的线性组合' 。使用参数调制分析，我们估计了每种模型响应情感刺激来预测唤醒相关脑区域中激活的能力。结果表明，在预测与唤醒相关的神经活动的能力方面，唤醒与价不能分开。
