Layer-Specific Physiological Features and Interlaminar Interactions in the Primary Visual Cortex of the Mouse

？ Multisite LFP recording and LFP-spike coupling identified physiological layers in V1 ？ The prominent 3–6 Hz LFP shared characteristic features with primate alpha rhythm ？ Spike transmission strength from layer 2/3 to layer 5 neurons was stronger during waking ？ A subset of layer 6 neurons was active selectively in the DOWN state of non-REM slee
