Supplmentary Figure 1. Subnetworks in developing isocortex. a Areal trace examples. Synchronized activations between hemispheres indicated by red links.
supplementaryFig-symmetry.ai Cortical domain activity exhibits bilateral symmetry. a Examples of domains exhibiting spatially symmetric activations. Notice most timepoints contain a mixture of symmetric and asymmetric domain activations. b Cortical active fraction timecourses for both hemispheres. c Hemispheric domain centers of mass for coactive frames in a recording along medial-lateral (ML) and anterior-posterior (AP) extents. Bottom left panels show the periods indicated by black bars at expanded view. Pearson's correlation: ML, p = 1.1591e-28; AP, p = 7.0982e-07. d Hemispheric autocorrelation and cross-correlation functions for cortical activity at all and short time lags. Notice the peaks above gaussian distributed noise (blue traces).
