In vivo assessment of human visual system connectivity with transcranial electrical stimulation during functional magnetic resonance imaging.

abstract：:How executive function training paradigms can be effectively designed to promote a transfer of the effects of interventions to untrained tasks remains unclear. Here, we tested the hypothesis that training with a complex task involving motor, perceptual and task-set control components would result in more transfer than...
