Correlational analyses of feedforward adaptation and feedback-based compensation in individuals with cerebellar degeneration (CD). A–D, Within the CD group, there were no correlations in behavioral measures obtained across (A, B) or within (C, D) motor domain. Plots show individual CD participants as red symbols (red diamonds, SCA6 and SCA8; red circles, other CD participants) and the mean of the control participants as a blue dot. To simplify interpretation, the sign of compensation in reaching has been flipped so that larger positive values reflect greater compensation, as for all other measures. A, Adaptation in reaching and speech. B, Compensation in reaching and speech. C, Adaptation and compensation in reaching. D, Adaptation and compensation in speech.
