Is the attention spotlight synchronised with the brain's theta waves?

- dr_dshiv 8y agoI saw a researcher present a model of theta as a siren light (vs strobe), that moves from the back of the brain to the front, in an oscillatory loop. Where theta is active, the whole of attention is integrating with the local input of the part. As a general principle, we look for "phase amplitude coupling" to describe the integration of fast (gamma) local oscillations with slower (theta) global oscillations. Another well established oscillatory model describes binding in visual perception -- which is based on the synchronization of 40hz inhibitory interneurons in different parts of the visual field. Different parts of the same object have a synchronized inhibitory input. Theory is called "binding by inhibition gating" or " communication through coherence"
