Figure 3.

Representative LFP Traces. Traces, filtered at 0–20 Hz, are shown for the intertrial delay period and during the running of the trials for a representative subject. For simplicity, traces are only shown for the last eight trials of the go east condition and the first eight trials of the go west condition and only the first 10 sec of intertrial delay period are shown. The scale bars indicates 1 sec and 1 mV. The average power spectra, in arbitrary units, for the LFPs recorded during the delay period (dotted) and the trials (dashed) are shown in the plot on the right.
