Gamma amplitude coupling to alpha phase from superficial layers of V1 and SEF. Conventions as in Fig. 5. A and B: TFRs and statistical comparisons for translaminar gamma coupling to alpha phase in L4 (V1, left) and L3 (SEF, right). C and D: same as A and B but for alpha phase from L2/3. V1 data show only minimal gamma modulation with alpha phase in superficial layers. In contrast, SEF gamma power was coupled to the local alpha phase within each respective laminar compartment. Note the phase difference in SEF's alpha-coupled gamma modulation compared with Fig. 5.
