The hierarchical model demonstrates dynamics of alpha-band traveling waves in the visual system, revealing roles for cortical connectivity and pulvinar engagement.
Key Points
The model reproduces dynamics of alpha-band traveling waves observed in EEG recordings.
Forward waves dominate during visual processing, while backward waves prevail at rest or during suppression.
Two distinct cortical sub-networks generate forward and backward waves, connected in infragranular layers.
Pulvinar engagement biases dynamics towards forward waves, indicating its role in cortical information flow.
