Spindle Bursts in Neonatal Rat Cerebral Cortex

Figure 2

Properties of spontaneous spindle bursts and gamma oscillations. (a) Spindle burst recorded in barrel cortex of a P1 rat (top) and corresponding MUA after 200 Hz high-pass filtering (below). Color-coded frequency plot shows the wavelet spectrum of the field potential recording at identical timescale. Fast Fourier Transformation (FFT) of the field potential recording illustrating the relative power of the displayed spindle burst with maximal power at 10 Hz frequency (bottom). (b) Gamma oscillation (top) recorded in barrel cortex of a P3 rat and corresponding MUA (below). Wavelet and FFT spectrum reveal prominent gamma activity between 30 and 50 Hz.
