Figure 5: LF = low frequency in absolute (ms2) (Panel A) and normalized units (nu) (Panel B), HF = high frequency in absolute (ms2) (Panel C) and normalized units (nu) (Panel D), and LF/HF ratio (Panel E). Response to classical music ms = milliseconds *P < 0.05 vs. control, **P < 0.05 vs. music, P < 0.01 vs. music, #P < 0.001 vs. control
