fMRI Investigation of Cortical and Subcortical Networks in the Learning of Abstract and Effector-Specific Representations of Motor Sequences

keypad. Display and Keypad rotations for both the visual and motor settings is
shown for the example sequence of normal setting shown in panel a. The
baseline was random hypersets arranged as 1x12 sequences in the (d) follow
condition. Subjects repeatedly practised the same hyperset for the sequence
tasks a - c, but random hypersets were generated for every trial of the follow
condition.

Behavioral Results.

Figure S2: Vertical lines in A and B demarcate the early, intermediate and
late stages each consisting of 6 blocks. A) Accuracy. Graph depicts the
average number of sets completed (out of a maximum of 6 sets in a hyperset)
per block, averaged across subjects. As learning progressed, the number of
sets completed (accuracy) increased significantly from early to late stage in all
the settings. Accuracy in the normal settings (NormalM and NormalV) was
similar throughout the experiment. Although accuracy in the early stage
seemed higher in the motor than in the visual setting, thereafter it remained
similar in both the settings. B) Set completion time. Graph depicts the average
set completion time (in sec) per block, averaged across subjects. As learning
progressed, it required significantly less time to perform a set. Again, while the
