Fig 2. Recurrent balanced network driven by oscillatory input.
Recurrently connected excitatory (E) and inhibitory (I) populations (Erdős-Rényi random network with connection probability p) receiving input from an external (X) excitatory population. Additionally, all neurons in the microcircuit receive a sinusoidal signal of amplitude hext and frequency ω, representing the oscillatory activity received from external brain areas.
