Dissecting abstract, modality-specific and experience-dependent coding of affect in the human brain

Emotion and perception are tightly intertwined, as affective experiences often arise from the appraisal of sensory information. Nonetheless, whether the brain encodes emotional instances using a sensory-specific code or in a more abstract manner is unclear. Here, we answer this question by measuring the association between emotion ratings collected during a unisensory or multisensory presentation of a full-length movie and brain activity recorded in typically-developed, congenitally blind and congenitally deaf participants. Emotional instances are encoded in a vast network encompassing sensory, prefrontal, and temporal cortices. Within this network, the ventromedial prefrontal cortex stores a categorical representation of emotion independent of modality and previous sensory experience, and the posterior superior temporal cortex maps the valence dimension using an abstract code. Sensory experience more than modality impacts how the brain organizes emotional information outside supramodal..., , , # Dissecting abstract, modality-specific, and experience-dependent coding of affect in the human brain

## Description of the data and file structure

#### Behavioral data and code

**behavioral/code/** -> all MATLAB functions needed to analyze the behavioral data (i.e., categorical and valence ratings collected during the auditory, visual, and multisensory experiments).

**behavioral/data/categorical_audio/** -> 20 folders (one for each participant) storing the categorical annotations of emotion collected during the auditory experiment. The folder also includes subs_demographics.csv, which stores participants' demographics. In each participant's folder, there are 6 MATLAB workspace files (*_run0?.mat) storing ratings of the affective experience for each run. In each workspace, there is a structure called *ReMoTa_Output*, which contains all behavioral data and experiment details. Specifically:
-*ReMoTa_Output.Date_Experiment* stores the date of the experiment.
-*ReMoTa_Output.Mo...

情绪与知觉紧密交织，情感体验往往源于对感官信息的评估。然而，大脑究竟是采用感官特异性编码（sensory-specific code）还是更抽象的方式来表征情绪实例，目前仍不明确。本研究通过分析完整时长电影以单感官、多感官形式呈现时采集的情绪评分，与典型发育、先天性失明及先天性失聪被试的脑活动之间的关联，解答了这一问题。

研究发现，情绪实例的编码涉及涵盖感觉皮层、前额叶皮层及颞叶皮层的广泛神经网络。在该网络中，腹内侧前额叶皮层（ventromedial prefrontal cortex）存储了不依赖感知通道与既往感官经验的情绪类别表征；而后颞上皮层（posterior superior temporal cortex）则通过抽象编码映射情绪的效价维度。相较于感知通道，感官经验对脑内超模态之外的情绪信息组织方式影响更为显著……
