Blood oxygenation level-dependent contrast response functions identify mechanisms of covert attention in early visual areas

Covert attention can lead to improved performance in perceptual tasks. The neural and functional mechanisms of covert attention are still under investigation. Using both rapid event-related and mixed designs, we measured the blood oxygenation level-dependent functional MRI contrast response function...
