摘要
针对织物舒适度领域中大脑感知机制尚不明确的问题,功能磁共振成像技术凭借其超高的空间分辨率在织物刺激脑感知表征领域表现出良好的技术优势。根据织物刺激的感知过程以及功能磁共振成像技术的表征原理,总结来自织物触觉刺激、视觉刺激、视-触觉跨模式刺激的大脑感知规律,并提出将此技术深入运用于脑感知表征研究时需要突破的一些难题和方向,期待以其客观、即时的优势为构建织物舒适度脑感知理论体系和满足纺织服装产品设计舒适性要求提供新思路与新方法。
At present,the brain perception mechanism in the field of fabric comfort is not clear,and the existing characterization technology of fabric comfort has not been quantified.Functional magnetic resonance imaging technology has shown good technical advantages in the field of fabric stimulation brain perception representation with its high spatial resolution,which is of great significance for exploring the brain perception mechanism of fabric comfort.By exploring the changes between stimulation signals and brain activation signals,fMRI technology can effectively and accurately identify the relevant brain regions under fabric stimulation,and complete the brain in situ perception representation of fabric comfort.This paper reviews the research status of brain perception of fabric stimulation based on fMRI technology from the three fields of tactile stimulation,visual stimulation,and visual-tactile cross-stimulation.Among them,the somatosensory cortex,motor cortex and ventral visual cortex are the relevant response brain regions for tactile stimulation,visual stimulation and visual-tactile cross-stimulation.The characteristic indicators are mainly activation intensity and activation proportion.At present,the study of brain perception of fabric stimulation based on fMRI technology has become a popular research topic.It has been confirmed that the activation point coordinates,activation intensity,activation proportion,functional connectivity and other information of relevant brain regions under fabric stimulation can effectively represent the brain perception of fabric stimulation,which provides great potential for in situ representation of fabric stimulation.Based on the principle of brain perception representation of fMRI technology,this paper summarizes the research status of brain perception of fMRI technology in fabric slight touch stimulation,contact pressure stimulation,visual stimulation,and visual-tactile cross-stimulation.It is concluded that SI,SII and motor cortex in the somatosensory cortex are related to sl
