Fig 4 — (a and b) Injecting Gaussian noise with the same mean and variance as the control signal does not result in suppression but rather in enhancement of oscillations. (c) Current injected into the somata of the neurons. Gray: Gaussian noise, red: DFC signal used in Fig 2a–2d. (d and e) Injecting strong Gaussian noise, σ = 14 mV, yields to suppression of the oscillatory activity. (f) The subthreshold dynamics of ten randomly chosen neurons reveal that this strong external noise results in very large fluctuations in the membrane (gray). By contrast, the fluctuations under DFC are significantly smaller (red).
