Figure 1.

Adaptation to visuomotor rotations. Curves show mean angular error as a function of block on different days. The height of the shaded areas represents ±1 SE. For clarity, we have shaded the area formed by joining confidence intervals between adjacent blocks. The top panel shows results for the control group who adapted to the same visuomotor rotation (A) on days 1 and 3. The bottom panels show results for the test group who also adapted to the opposing visuomotor rotation (B) on day 2.
