项目摘要
The notion of predictive coding assumes that perception is an iterative process between prior knowledge and sensory feedback. To date, however, this perspective has been applied primarily to exteroceptive perception, such as vision and audition, as well as action. More recently, this predictive, inferential framework has theoretically also been suggested on interoception, the internal physiological condition the body is in. On this view subjective feeling states (i.e. emotion and self- awareness) are generated by active top-down inference on the internal and external causes of interoceptive afferents. The proposed project will provide a direct empirical investigation of this hypothesis by studying brain activity underlying interoceptive prediction by means of EEG and fMRI methodology in an established repetition suppression paradigm. We expect neural attenuation of interoceptive signals in response to expected compared to unexpected changes of interoceptive signals. Further studies shall investigate the specific role of the motor system in predicting sensory and bodily afferences. Finally, the neural correlates of attention to predictive exteroceptive and interoceptive signals shall be specified. The results of this project can help to illuminate interactions between cognition, perception, emotion as well as aspects of self-awareness.
预测编码的概念假设感知是先验知识和感觉反馈之间的迭代过程。然而,到目前为止,这种观点主要应用于外感受性知觉,如视觉和听觉,以及行动。最近,这种预测性的推理框架在理论上也被提出来用于内感受,即身体所处的内部生理状态。根据这种观点,主观感觉状态(即情绪和自我意识)是通过对内感受传入的内部和外部原因进行自上而下的积极推理而产生的。拟议的项目将提供一个直接的实证调查这一假设,通过研究脑活动的基础内感受性预测的EEG和功能磁共振成像方法在一个既定的重复抑制范式。我们预期内感受信号的神经衰减响应于内感受信号的预期变化和意外变化。进一步的研究将探讨运动系统在预测感觉和身体传入中的特殊作用。最后,神经相关的注意力预测外感受性和内感受性信号应予以规定。该项目的结果可以帮助阐明认知,感知,情感以及自我意识方面之间的相互作用。
