Brain Dynamics Underlying the Nonlinear Threshold for Access to Consciousness
PLoS Biology September 25, 2007 Antoine del Cul, S. Baillet, S. Dehaene
When a flashed stimulus is followed by a backward mask, subjects fail to perceive it unless the target-mask interval exceeds a threshold duration of about 50 ms. Models of conscious access postulate that this threshold is associated with the time needed to establish sustained activity in recurrent cortical loops, but the brain areas involved and their timing remain debated. We used high-density...
