Fig. 5. Gamma synchrony and long-range dipole correlations. ( A ) Voltage/time plot of γ synchrony over 250 ms ( fig. 1D,). ( B ) Three “40-Hz”γ cycles (75 ms) of dendritic protein oscillations ( figs. 3C and 4C ) in which spatially separated proteins ( e.g. , frontal and occipital brain regions) are coupled via long-range London force quantum dipole correlations, accounting for zero-phase-lag γ synchrony. Such long-range dipole correlations may occur through gap junction–connected dendrites.
