Column‐based model of electric field excitation of cerebral cortex
A model to explain the orientation selectivity of the neurophysiologic effects of electric‐field
transients applied to cerebral cortex is proposed and supported with neuroimaging evidence. …

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