Inter-areal coherence is predicted by connectivity and power
(A) In the Synaptic-Source-Mixing model, the receiver LFP is modeled as a linear superposition of intrinsic activity and afferent inputs from the sender, weighted by w. Shown are power, coherence, Granger-causality spectra, and the transfer function.
(B and C) Coherence as a function of the SOS (sender oscillation strength) and coupling weight.
(C) Data: dashes. Model: solid.
(D) Effect of coupling weight and SOS on coherence.
(E) SSM model fit of 7B-F5 coherence, with w = 0.069.
