Methods Twenty-three patients with space-occupying lesions in motor cortex and nine health volunteers were underwent both conventional magnetic resonance imaging(MRI) and functional magnetic resonance imaging(fMRI) examinations. Results Primary motor cortex (M1) in twenty patients who with initiative stimulation during motor task showed displacement of the activity in the affected hemisphere. The activation volumes of M1 in the affected hemisphere were significantly smaller compared with the contralateral side (n=15). Activation of ipsilateral M1 and premotor cortex (PMC) of both hemispheres were showed in a part of the cases. Two of the three patients underwent passive stimulation showed the activity of M1. Conclusions fMRI is an effective method in localizing motor cortex, and it is valuable for the evaluation of the motor deficit in patients.Read More
