Emergence and fragmentation of the alpha-band driven by neuronal network dynamics
Fig 8
Computational principle underlying the α-band dynamics.
A: Multiscale models 1. synaptic level: short-term facilitation and depression mechanisms, 2. neuronal population: mean voltage fluctuations and 3. interactions between different brain regions (thalamus and cortex, models 5 and 6) resulting in the different activity patterns observed in EEG at a global scale. B: α-band emerges in the Up-state due to noise but can be altered by external inputs.
