Fig. 4: Effect of macroscopic gradient of excitation on timescale localization.
From: A hierarchy of time constants and reliable signal propagation in the marmoset cerebral cortex
a Scatterplot of Inverse Participation Ratio (IPR) and θ for each eigenmode of the modeled dynamic system. Left panel: plot under the control condition. Right panel: plot under the condition that the composite gradient of excitation is absent. The color-coded timescale was after taken the logarithm using the natural base e. b Change of IPR (left panel) and θ (right panel) as the gradient slope increases. c Visualization of a representative eigenmode (the fastest eigenmode) in the control condition, with values of the eigenmode plotted aside. The size of each black dot codes the magnitude of the corresponding element in an eigenmode. d Similar to (c), under the condition that the composite gradient of excitation is absent. The eigenmodes correspond to the black-circled dot in (a).
