The assertion that network properties are at the basis of the MEG response generation can, for example, be studied by variations of the parabelt connections of \(\widetilde{W}_{\tiny\mbox{ee,lat}}\) while keeping all other connections unchanged. (\(\bf{A}\)) Enlarged view of the original connections of the two parabelt fields from FigureĀ \ref{fig:AC_w_ee}. (\(\bf{B}\)) Modified parabelt connections computed by randomly varying the amplitude of the Gaussian distribution describing the strength of the connections. The color bars indicate the connection strengths. (\(\bf{C}-{E}\)) Corresponding simulations of the areal contributions to the MEG signal from core, belt and parabelt, respectively. The solid lines are simulations based on \(\widetilde{W}_{\tiny\mbox{ee,lat}}\) with the original (default) parabelt connections; these waveforms are identical to those shown in FigureĀ \ref{fig:MEG_field_area}B. The dashed lines are simulations using the modified connection pattern shown in (B). The modification of the parabelt connections affects the dynamics (waveforms) in all auditory areas, even in the core fields. \(\bf(F)\) Simulations using the original and modified parabelt connection pattern, respectively, result in marked differences in the morphology of the MEG response, with a distinct effect on the M100-peak magnitude and latency.
