Extended Data Fig. 7: Evolution of synaptic weights connected to dendritic compartments for matched and independent E & I.

a, Weights of co-active (green) and uncorrelated (grey) excitatory inputs with size of co-active excitatory group and distance of dendritic compartment from the soma indicated by ‘group size’ and ‘d’, respectively. b, Weights of co-active (green; same activity pattern as co-active excitatory group) and uncorrelated (grey) inhibitory inputs. Size of the co-active inhibitory group was kept fixed at half of the inhibitory population. c, Same as panel a, but when inhibitory inputs are independent of excitatory ones. d, Same as in panel b, but with no correlation between excitatory and inhibitory inputs.
