Changes occur in resting state network of motor system during 4 weeks of motor skill learning

L Ma, S Narayana, DA Robin, PT Fox, J Xiong - Neuroimage, 2011 - Elsevier
We tested whether the resting state functional connectivity of the motor system changed during
4weeks of motor skill learning using functional magnetic resonance imaging (fMRI). Ten …

Changes in regional activity are accompanied with changes in inter-regional connectivity during 4 weeks motor learning

L Ma, B Wang, S Narayana, E Hazeltine, X Chen… - Brain research, 2010 - Elsevier
Structural equation modeling (SEM) and fMRI were used to test whether changes in the regional
activity are accompanied by changes in the inter-regional connectivity as motor practice …

Concurrent TMS to the primary motor cortex augments slow motor learning

S Narayana, W Zhang, W Rogers, C Strickland… - Neuroimage, 2014 - Elsevier
Transcranial magnetic stimulation (TMS) has shown promise as a treatment tool, with one
FDA approved use. While TMS alone is able to up- (or down-) regulate a targeted neural …

CBF changes during brain activation: fMRI vs. PET

CM Feng, S Narayana, JL Lancaster, PA Jerabek… - Neuroimage, 2004 - Elsevier
The changes in regional cerebral blood flow (rCBF) associated with the changes in neuronal
activity are routinely measured both by positron emission tomography (PET) and functional …

Long-term motor training induced changes in regional cerebral blood flow in both task and resting states

J Xiong, L Ma, B Wang, S Narayana, EP Duff, GF Egan… - Neuroimage, 2009 - Elsevier
Neuroimaging studies of functional activation often only reflect differentiated involvement of
brain regions compared between task performance and control states. Signals common for …
