Baseline cortical excitability determines whether TMS disrupts or facilitates behavior.
Transcranial magnetic stimulation (TMS) is increasingly used to modify brain activity noninvasively and to study brain-behavior relations. However, results can be variable and the conditions that affect the functional efficacy of TMS remain unclear. Here we show that on-line TMS can either facilitate or suppress perceptual functions depending on the baseline level of activity of the targeted br...
متن کاملCrowding by Invisible Flankers
BACKGROUND Human object recognition degrades sharply as the target object moves from central vision into peripheral vision. In particular, one's ability to recognize a peripheral target is severely impaired by the presence of flanking objects, a phenomenon known as visual crowding. Recent studies on how visual awareness of flanker existence influences crowding had shown mixed results. More impo...
متن کاملCrowding and the tilt illusion: toward a unified account.
Crowding, the difficult identification of peripherally viewed targets amidst similar distractors, has been explained as a compulsory pooling of target and distractor features. The tilt illusion, in which the difference between two adjacent gratings' orientations is exaggerated, has also been explained by pooling (of Mexican-hat-shaped population responses). In an attempt to establish both pheno...

متن کاملGeneration Gap: Illusion or Reality?
Values have very important functions in any society. The significance becomes so clear when a society has been exposed to changes and strengthening social cohesion is viewed as an essential subject. Great changes as the Islamic Revolution and the Imposed War have been happened in Iran during last several decades. In this line, generations can be understood via direct or indirect experience of...
