Collective dynamics of the coupled system. (a) Time traces of the net PSP y(t) = y₁(t) − y₂(t) of both NMs working at different frequencies: at 4.5 Hz within the theta band (blue online, dark grey in print), and at 11 Hz within the alpha band (red online, grey in print). The LFP of the neural network (turquoise online, light grey in print) oscillates in the gamma range around 45 Hz. The three neural ensembles are uncoupled. (b) Time traces of the PSPs of both NM models and LEP of the neural network when the system is coupled (k = 1). Averaged maximum cross covariance (c) and frequency mismatch (d) between the PSP time traces of the NMs for increasing inter-scale coupling strength k. (Online version in colour.)
