Figure 5.
Beta frequency range power spectra of the local field potentials recorded from MI and PMd during active movement and passive observation of movement. A, Mean ± SE power in the 10–25 Hz range of the LFP averaged over multiple segments and channels during active movement (dark blue trace), observation of target and cursor (orange trace), observation of target only (red trace), and observation of cursor only (cyan trace). B, Integrated mean power (integrated between 10 and 25 Hz) as a function of experimental condition. Integrated power during each observation condition is statistically different from integrated power during active movement condition for monkeys MK and RX. For monkey RS, integrated power during observation of target only and observation of cursor only is statistically different from integrated power during active movement. MI data shown for monkeys RS and MK, and PMd data shown for monkey RX.
