Figure 2. Memory period αβ power correlates with behavioral performance.

A) The αβ power of a sample LFP signal during the memory period is predictive of the monkey’s behavior. (Top) Saccade landing points for high αβ power trials and low αβ power trials are shown in light and dark colors, respectively; the cross is the fixation point and the black circle is the remembered target location. The distance between saccadic landing points and the remembered target location (saccade error) is smaller for high αβ power trials compared to low αβ power trials in this session. The histogram shows the distributions of pairwise distances between saccadic landing points (saccade scatter) for high (green) and low (purple) αβ power trials in this session. B–D) A comparison of saccade scatter, error and velocity for high αβ power trials vs. low αβ power trials, across all memory-selective LFP signals (n=169). Scatter plots show the mean saccade scatter, error, and velocity values for high vs. low αβ power trials for each memory-selective LFP signal. Diagonal histograms show the distribution of differences between conditions for each performance measure. The data from m1 is represented by rectangles and circles indicate the data from m2.
