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.

在成功的记忆编码过程中,扫视被锁相到枕骨和颞颞叶的α振荡

有效的视觉信息采样需要协调眼球运动和持续的脑震荡。使用颅内和脑磁图(MEG)记录,我们显示扫视被锁定到视觉阿尔法振动的相位,并且这种协调与视觉场景的成功记忆编码有关。此外,参与这种协调的海马旁和脾后皮层反映了有效的视觉到记忆的映射,突显了神经振荡对于视觉和记忆域之间相互作用的重要性。
