Fig. 5.

A: M1 LFP voltages averaged over trials for each of the 8 target locations during 1 experimental session (monkey A). Numbers of trials are indicated by n above each subplot. LFP shown here was band-pass filtered between 1 and 10 Hz with a finite impulse response filter with a Kaiser window. Shaded gray lines indicate ±1 SE of the LFP voltages. Vertical gray line at time 0 indicates the start of arm movement. Arrow in polar plot (center) shows the PD of the LFP signal during the MOVE period (same conventions as Fig. 4). B: examples of LFP recorded on 3 individual trials of the experiment in each monkey. LFP shown here contains the full 0.3- to 500-Hz signal. Note that high-frequency (“gamma”) activity is associated with the MOVE epoch.
