Using task-based fMRI to understand attentional mechanisms in healthy controls
Background. Hemispatial neglect is a complex syndrome associated with a reduced capability to orient attentional resources toward the contralateral side of space, that involves a collection of symptoms. We used three functional magnetic resonance imaging (fMRI) tasks (i.e., visual search, VS; line bisection, LB; extinction, EX), performed by 25 healthy subjects, to investigate the behavioral and neural correlates under these symptoms. Procedure. During fMRI, participants were presented with: 1.
