• TLDR：Paired MEG occlusion shows that 15 of 19 stimulus features contribute, with the largest effects for silence, sound intensity, vowels, and acoustic onsets, indicating that activity without narrative structure carries less recoverable information than activity during coherent speech.

• 标题中文：感知语音的可解释 MEG 解码：皮层源与驱动检索的刺激特征
• TLDR中文：配对 MEG 掩蔽实验表明，19 个刺激特征中有 15 个有贡献，其中静音、声音强度、元音和声学起始的影响最大；说明缺乏叙事结构的神经活动相比连贯语音下的活动，可恢复的信息更少。
