EEG Frequency-Tagging and Input-Output Comparison in Rhythm Perception.

abstract：:This study aimed to finding modality-independent event-related potentials (ERP) modulations related to spatial attention by minimising several possible methodological constrains which may account for the rareness of this finding in past spatial attention ERP research. ERP were recorded while subjects performed a shift...
