A new closed-loop system based on brain state monitoring accurately controls unconsciousness by automating doses of the anesthetic drug propofol every 20 seconds.
The brain creates distinct spaces in the cortex for each general rule and controls those patches with brain rhythms, a concept called “spatial computing.” This explains how the brain can easily sustain a consistent understanding of a process even when the specific contents keep changing.
Early-stage clinical studies testing the safety and efficacy of 40-hertz sensory stimulation to treat Alzheimer’s disease found that the potential therapy was well-tolerated and was associated with some significant neurological and behavioral benefits among a small cohort of participants.
Holding information in mind is accompanied by coordination of rotating brain waves in the prefrontal cortex, a phenomenon that may convey specific advantages, a new study suggests. The work was performed by scientists at the Picower Institute of Learning and Memory at MIT.
