Expression of a single oscillation frequency with strong fluctuations in power.

Abstract

<p>Shown are the Fourier transform (<b>a, d</b>), wavelet transform (<b>b, e</b>) and raster diagram of cell firing (<b>c, f</b>) from the excitatory population of the target network (the slow network in <b>a–c</b> and the fast network in <b>d–f</b>). The inset in <b>a</b> shows the connectivity scheme from the fast to the slow network (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0100899#pone.0100899.s004" target="_blank">Fig. S4C</a>2), in which the Ie connection had . In the time interval shown, the slow network expressed its own base frequency (20.4 Hz) but with strong fluctuations in power. The inset in <b>d</b> shows the connectivity scheme from the slow to the fast network (see Fig. 5b2), in which the eI connection had . The fast network expressed the base frequency of the slow network with strong fluctuations in power.</p
