Abstract: 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 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, visual-tactile cross-stimulation. It is concluded that SI, SII and motor cortex in the somatosensory cortex are related to slight touch stimulation and contact pressure stimulation of fabrics. Among them, SI is related to smoothness and softness, and SI, SII and motor cortex are related to roughness, adhesion and itching. On the right side, SII is the fabric comfortable pressure perception brain area, SI and amygdala are the fabric uncomfortable pressure perception brain area, while amygdala is the fabric compression pressure perception brain area. The changes of functional connectivity between SI and SII are related to the duration of stress stimulation. The ventral visual cortex brain network is not only a relevant brain area for the perception of fabric visual stimuli, but also a multi-sensory representation brain area for material properties. The fusiform gyrus is not only sensitive to material category perception, but also related to visual short-term memory. In the future fabric stimulation process based on fMRI technology, it is important to master and control or eliminate interference factors for fabric comfort representation research. However, in the field of thermal and wet stimulation of fabrics, the brain mechanism of short-term memory of fabric properties, the flow process and effective connection of characteristic activated brain regions, and the dynamic adaptation and regulation mechanism of brain regions under long-term stimulation need to be further explored.
