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



Figure 6. Brain-behavior correlation at Pre-SMA. Voxel data were extracted from a 3
mm spherical VOI defined at Pre-SMA (Talairach coordinates x=-4, y=8, z=46 mm;
Table 3b) and the average BOLD signal for each of the six sessions was calculated for
each subject separately for
motor and visual experiments. Average performance
measures were calculated for the six sessions for each subject separately for the two
experiments. Graph depicts the scatter plot between the normalized behavioral
measure (accuracy: left panel and set completion time: right panel) and the BOLD
signal for each subject (1 - 9 and a - e). The regression line fits the average values of
behavioral measure and the BOLD signal. The top panel shows the results for
motor
setting and the bottom panel for the visual setting. The correlation results are: Motor
[Accuracy: R = 0.39, p=0.44; Time: R = -0.38, p=0.46]; Visual [Accuracy: R = 0.99,
p<.0001; Time: R = -0.99, p<.0001]. Clearly, the activity in pre-SMA is closely
related to performance improvements in the
visual setting but not the motor setting.
