Coordinating the activity of the thalamus, cingulate gyrus, prefrontal cortex and brainstem regulate consciousness through our executive attention. Positive feedback signals through iterative algorhythms is carried out in the thalamocortical loop and receives experimental confirmation by about 40 hertz. As […]
