How single neuron properties shape chaotic dynamics and signal transmission in random neural networks

Correlation time and effect of recurrent connections.
a: Correlation time (blue solid line) and Q-factor (dashed line) as a function of the connectivity strength. The weakest connectivity level plotted is g = 1.01gc(γ, β). Adaptation parameters: γ = 0.1 and β = 1. The dash-dotted horizontal line indicates the Q-factor of a single unit with the same adaptation parameters, driven by white noise. b: Correlation time (blue) and Q-factor (black, dash-dotted line) as a function of the adaptation timescale τa ≔ γ−1. Both the recurrent network (solid line) and the single unit driven by white noise (dashed line) scale with τa. β = 1 and g = 1.5gc(γ, β).
