Figure 3. Behavioral improvement and the increase of decoder similarities across sessions.

(A) Both monkeys show significant improvement in the traveling time and distance as they learn. The circles represent the median and the error bars show the interquartile range of the medians. (B) Increased correlations between decoders trained in earlier sessions and the last session. (left, Monkey K; right, Monkey M (C) Both monkeys demonstrate impaired performance once their decoded movement commands were inverted (forward now becomes backward, and right turn becomes left turn). The bar graph shows the median and the error bars indicate the interquartile range of the medians.
