Fig. 6: Dependence of local but not global timescales on the spatial network structure.

From: Intrinsic timescales in the visual cortex change with selective attention and reflect spatial connectivity

Fig. 6

a Schematic of local (r = 1) and dispersed (r > 1) spatial connectivity in the network model. Each unit (blue) is connected to 8 other units (pink) selected randomly within the connectivity radius r (brown line). b Shapes of the autocorrelations of individual units (AC) reflect the underlying local connectivity structure. Interaction timescales disappear and the self-excitation timescale (τself) dominates local autocorrelations when the connectivity radius increases while the connection strengths are kept constant (ps = 0.88, 8pr = 0.11, pext = 10−4). The autocorrelation of the global network activity (ACglobal, inset) does not depend on the connectivity structure. Source data are provided as a Source Data file.
