Role of connectivity anisotropies in the dynamics of cultured neuronal networks

Fig 5

Effects of spatial anisotropy and external noise intensity on dynamics.

(A) Dynamical richness Θ as a function of obstacle height h and noise intensity σ for the Tracks condition. Data shown is averaged over three reproductions. White-circled numbers relate to highlighted plots in panel (B). By definition , but typically . A value of indicates dynamically rich activity. (B) Representative raster-plots of the simulation runs with parameters as marked in panel (A), illustrating the differences in activity dynamics for the different parameter values and measured dynamical richness. For all panels . Panel A shows averaged data of 3 independent simulation runs per parameter combination.
