Session by session correlation of LGN-V1 PPC and V1 power, and schematic of LGN-V1 connectivity. A, Correlation spectrum between LGN-V1 PPC and V1 power. Dashed lines denote correlation values that are significant at p < 0.05. B, C, Power by PPC scatter plots of the V1 frequencies (B, 2–10 Hz; C, 26–48 Hz) that are significantly positively (B) and negatively (C) correlated with LGN-V1 PPC across sessions (N = 21). D, Schematic of functional and anatomical connections. The lines interconnecting areas or subpopulations indicate anatomical connections. Dotted lines indicate secondary (weaker) projections. Where functional data exist to indicate which frequency bands mediate the synaptic interactions (Maier et al., 2010; Buffalo et al., 2011; Xing et al., 2012b), the corresponding frequency is indicated.
