Fig. 6.

The effects of OLBNP at 0.03, 0.05, and 0.10 Hz on OAP power at 0.0083 Hz due to AF. Data are averaged over all subjects and are logarithmic as in Fig. 5, with results expressed as decibels. A: AF alone compared with baseline (solid bars) has no effect on OAP power at OLBNP frequencies. AF is followed by OLBNP (open bars), while flexion continues. B: OLBNP is first applied (open bars) and maintained during subsequent AF. Logarithmic OAP power at 0.0083 Hz is increased at 0.03 (P < 0.025) and 0.05 Hz (P < 0.05). Increased power is reversed by the addition of AF to LBNP (shaded bars). Values are means ± SE. *Significant difference of the comparison.
