Vehicle networks do not show large power distributions within low- and high-frequency networks.

<p>Short time, Fourier transform based time-frequency analyses were performed on one-minute epochs of low-pass filtered (top set) and high-pass filtered (bottom set) data from one representative electrode. Each set is a montage of three images in which the top image corresponds to baseline activity, the middle image corresponds to activity one day after treatment and the bottom image is the activity that was recorded four days after treatment. Within each image are vertical striations in which each striation is a color map that represents the power of the frequency present within the electrode. Red corresponds to high power and blue is low power. In both the low-pass filtered and high-pass filtered montages, the activity does not appreciably change before and after treatment and the power within each frequency regime is low.
