Discrimination of Tourette Syndrome Based on the Spatial Patterns of the Resting-State EEG Network.

abstract：:The attentional blink (AB) is a transient attentional deficit that occurs when two stimuli that must both be detected are presented within an interval of less than 500 ms. Event-related potential (ERP) investigations have suggested that the AB affects a specific component, the P3, which is suppressed when targets are ...
