Exploring how theta-gamma brain waves affect memory formation and cognitive control. This could lead to therapies for memory deficits and cognitive enhancement strategies.
Brain waves influence cognitive control and memory formation, informing how the brain manages memory.
Phase-amplitude coupling neurons synchronize with brain waves, aiding cognitive control and memory retrieval.Have you ever put your keys down and then completely forgotten where to find them? The brain has to work hard to protect information in your working memory from distractions. How this process works has, until recently, been unclear. Apublished in Nature looked at the interactions between the front part of the brain that controls thoughts and the hippocampus, which is important for memory.
The hippocampus and the prefrontal cortex are two important brain regions in memory formation. During memory formation, the hippocampus and prefrontal cortex communicate via brain waves of different frequencies . Beta waves reinforce correct associations, while theta waves weaken incorrect ones, guiding what the brain learns.
Each session used new pictures from various categories like faces, animals, and cars, ensuring freshness. Harder rounds challenged patients with three pictures instead of one, maintaining consistent time limits for memory recall. Mixing categories prevented reliance on familiarity, encouraging active memory use over recognition.Electrodes with at least eight wires recorded brain activity across various frequencies.
