摘要: Knowledge of an object's material composition (i.e., what it is made of) alters how we interact with that object. Seeing the bright glint or hearing metallic crinkle a foil plate for example, confers information about object before have even touched it. Recent research indicates medial aspect ventral visual pathway sensitive to surface properties objects. In present functional magnetic resonance imaging (fMRI) study, investigated whether also derived from sound alone. Relative scrambled sounds and non-verbal human vocalizations, audio recordings materials being manipulated crumpled) in someone's hands elicited greater BOLD activity right parahippocampal cortex neurologically intact listeners, as well cortically blind participant. Additional left inferior parietal lobe was observed group. Taken together, these results support ventro-medial specialized processing objects, suggest there are sub-regions within this subserve acoustically-derived composition.
