Unique cortical physiology associated with ipsilateral hand movements and neuroprosthetic implications.
BACKGROUND AND PURPOSE Brain computer interfaces (BCIs) offer little direct benefit to patients with hemispheric stroke because current platforms rely on signals derived from the contralateral motor cortex (the same region injured by the stroke). For BCIs to assist hemiparetic patients, the implant must use unaffected cortex ipsilateral to the affected limb. This requires the identification of ...
متن کاملCortical representation of ipsilateral arm movements in monkey and man.
A fundamental organizational principle of the primate motor system is cortical control of contralateral limb movements. Motor areas also appear to play a role in the control of ipsilateral limb movements. Several studies in monkeys have shown that individual neurons in primary motor cortex (M1) may represent, on average, the direction of movements of the ipsilateral arm. Given the increasing bo...
متن کاملTwo Distinct Ipsilateral Cortical Representations for Individuated Finger Movements
Movements of the upper limb are controlled mostly through the contralateral hemisphere. Although overall activity changes in the ipsilateral motor cortex have been reported, their functional significance remains unclear. Using human functional imaging, we analyzed neural finger representations by studying differences in fine-grained activation patterns for single isometric finger presses. We de...

until the end of August 2008. The SINE program is affiliated with the Sensory Motor Performance Program (SMPP) at the Rehabilitation Institute of Chicago (RIC) and the Biomedical Engineering program at Northwestern University. I worked in the Neuralplasticity Laboratory, which is a part of the SMPP located at the RIC. I worked under Dr. Stinear and Dr. Madhavan to test protocols developed by my...
