The lateral-occipital tactile-visual area (LOtv) is activated when objects are recognized by vision or touch. We report here that the LOtv is also activated in sighted and blind humans who recognize objects by extracting shape information from visual-to-auditory sensory substitution soundscapes. Recognizing objects by their typical sounds or learning to associate specific soundscapes with specific objects do not activate this region. This suggests that LOtv is driven by the presence of shape information.
当通过视觉或触觉识别物体时，枕外侧触觉视觉区（LOtv）会被激活。我们在此报告，在有视力的人和盲人中，当他们通过从视觉到听觉的感官替代音景中提取形状信息来识别物体时，LOtv也会被激活。通过物体的典型声音识别物体或学习将特定音景与特定物体联系起来不会激活该区域。这表明LOtv是由形状信息的存在驱动的。
