Abstract

Original Research

introduction :

Tactile perception of textiles emerges from the interaction between the physical properties of material surfaces, cutaneous mechanoreceptors, and neural systems involved in somatosensory and higher-order processing. Textile characteristics such as surface texture, roughness, softness, friction, thickness, and structural properties can shape subjective tactile experience. Neuroimaging and electrophysiological studies further indicate that different tactile textile stimuli may be associated with distinct patterns of neural activity. Synthesizing this evidence may help clarify the relationships among measurable textile properties, subjective perception, and neural responses.

Methods:

This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. PubMed, Web of Science, Scopus, and Google Scholar were searched using combinations of terms related to textiles/fabrics, tactile perception, texture, touch, brain activation, functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and somatosensory processing. Human studies examining relationships between physical or perceptual characteristics of textiles and sensory, cognitive, neurophysiological, or neuroimaging responses were considered. Data on textile characteristics, tactile stimulation procedures, perceptual measures, neurophysiological or neuroimaging methods, and implicated brain regions were extracted and qualitatively synthesized.

Results:

The available evidence indicates that tactile texture processing recruits a distributed neural network extending beyond the primary somatosensory cortex. Neuroimaging studies of texture perception implicate the primary and secondary somatosensory cortices, posterior insula, premotor cortex, and supplementary motor cortex. Studies specifically examining fabrics further demonstrate that different textile properties and compositions are associated with differences in subjective dimensions such as roughness, softness, slipperiness, and related tactile qualities, as well as with differential patterns of cortical activation. fMRI studies comparing active exploration of different fabrics have particularly implicated the primary and secondary somatosensory cortices, including the parietal operculum, in textile discrimination. EEG studies likewise show that fabrics differing in surface characteristics or material composition can elicit distinguishable electrophysiological responses, including differences in event-related potentials and spectral activity associated with fabric–skin interaction and subjective tactile perception.

Conclusion:

Current evidence supports an association between the physical and perceptual characteristics of textiles and distinguishable sensory and neural responses. Brain-mapping approaches therefore provide a useful framework for investigating how objectively measurable textile properties relate to subjective tactile experience and neural processing. Future studies integrating standardized textile characterization with multimodal neurophysiological and neuroimaging measures may help clarify individual differences in tactile processing and provide an evidence base for the development of textiles tailored to specific sensory requirements.
