Attention plays a crucial role in higher cognition in the presence of limited resources. We study attentional mechanisms producing sequential switching between interacting mental modalities. Our model uses dissipative dynamical systems of coupled oscillators modeling various parts of the brain. The dynamics can manifest winnerless competition (WLC) between the oscillators with switching between different...
Experiments conducted in brains by electroencephalographic and magnetoencephalographic techniques reveal widespread coherent oscillations. The oscillations over multiple frequency bands overlap and result in signals with broad spectra. Previous studies showed that various frequencies can be modeled by probabilistic cellular automata with coupled inhibitory and excitatory interactions. In this work...
