Practical scan-length considerations for mapping upper limb movements to the somatosensory/motor cortex at 7T: A pilot study.

ABSTRACT: The relationship between motor cortex (M1) and upper limb movements has been investigated extensively using functional MRI (fMRI). While most research has focused on applications, very few studies have focused on practical aspects of developing the fMRI protocol. Thus, the effect of scan length on M1 activations during various upper limb movements remains unclear. Scan length constraints are important for conducting motor experiments within a 60- or 90-minute scan session. We targeted this gap in the literature in this pilot study by investigating 7T fMRI activations in a male participant while performing eight different upper limb movements (of the fingers, wrist, and elbow) across 16 task runs (8 with the left arm, 8 with the right arm, 88 minutes total fMRI duration).
