Abstract
En 中文
• MEG reveals thalamus→A1→V1 sequential activation within 50 ms of auditory onset • V1 activates 10–15 ms after A1, consistent with a monosynaptic A1-to-V1 pathway • Auditory-evoked V1 responses are significantly larger in congenitally blind subjects • Alpha-band connectivity from A1 to V1 and thalamus to V1 is enhanced in blindness • Auditory cross-modal plasticity relies on a different route than tactile plasticity
