Results of simulations of model in Fig 1 using selected values of the parameters appearing in Eqs (4)–(7).

Parameter values (Δϕ, Δψ in radians) are in the leftmost seven columns, output values in the rightmost four columns. “sig noise” is signal noise; “max sigoe,” the maximum signal onset effect, is the maximum of the positive part of the oscillation at V2 minus that at V1, i.e., max(V2+ − V1+), between signal onset and signal onset + 250 ms; ‘extended sigoe,’ the extended signal onset effect, is the mean of the positive part of the oscillation between time at maximum −50 ms and time at maximum + 50 ms at V2 minus that at V1; MI is mutual information between the phases of V1 and V2 after signal onset until the end of the run. All output values in the table, ρ, max sigoe, extended sigoe, and MI, are the means of 10 realizations, with standard errors approximately 0.01, 0.95, 0.32, and 0.02 resp.
