Efficient sampling of visual information requires a coordination of eye movements and ongoing brain oscillations. Using intracranial and magnetoencephalography (MEG) recordings, we show that saccades are locked to the phase of visual alpha oscillations and that this coordination is related to successful mnemonic encoding of visual scenes. Furthermore, parahippocampal and retrosplenial cortex involvement in this coordination reflects effective vision-to-memory mapping, highlighting the importance of neural oscillations for the interaction between visual and memory domains.
有效的视觉信息采样需要眼球运动和大脑持续振荡的协调。我们通过颅内和脑磁图（MEG）记录表明，眼跳与视觉α振荡的相位锁定，并且这种协调与视觉场景的成功记忆编码有关。此外，内嗅皮层和后扣带回皮层在这种协调中的参与反映了有效的视觉到记忆的映射，突出了神经振荡对于视觉和记忆域之间相互作用的重要性。
