Abstract

Persichetti et al. use a non-BOLD fMRI method called vascular space occupancy (VASO) to show that whereas actual hand movements evoke responses in superficial and deep layers of M1, imagined hand movements evoke responses in superficial layers only. Imagined movements also produce layer-specific repetition effects on subsequently executed movements.
