Connectivity indices. (A1) Hyperconnectivity for inter-somatic distances smaller than 50 μm. (A2) Hyperplasticity for inter-somatic distances between 50 and 200 μm. (B1) Connection probability in (25 μm) discrete zones, before sodium glutamate perfusion. (B2) Connection probability in (25 μm) discrete zones, after sodium glutamate perfusion. (C1) Emergence index, showing higher tendency for appearances of new connections at somata separation between 50 and 200 μm. (C2) Emergence index calculated along (25 μm) discrete inter-soma distances, showing significant difference at somatic separation between 75 and 100 μm.
