Fig 6. Cost-efficient information capacity in the critical region.

(A) Average excitatory firing rate v_E; (B) Energy efficiency η_sim in analog scenario at r = 0; (C, D) Energy efficiency η_sim at various r (colors) and average excitatory firing rate v_E (black) vs. E—E Synchrony in both binary (C) and analog (D) scenarios. Cost-efficiency is achieved robustly in the critical region across the empirical range of r. n = 40 for all patterns. (A, B) in the parameter space (τ_{d_e}, τ_{d_i}) (unit: ms).
