How brain waves guide memory formation
Our brains generate a constant hum of activity: As neurons fire, they produce brain waves that oscillate at different frequencies. Long thought to be merely a byproduct of neuron activity, recent studies suggest that these waves may play a critical role in communication between different parts of the brain. A new study from MIT neuroscientists adds to that evidence. The researchers found that two brain regions that are key to learning — the hippocampus and the prefrontal cortex — use two different brain-wave frequencies to communicate as the brain learns to associate unrelated objects. Whenever the brain correctly links the objects, the waves oscillate at a higher frequency, called “beta,” and when the guess is incorrect, the waves oscillate at a lower “theta” frequency.
Mental Heuristics Page
A heuristic is a "rule-of-thumb", advice that helps an AI program or human think and act more efficiently by directing thinking in an useful direction. Some of these heuristics are age-old wisdom, bordering on cliche, but most are actually helpful. If you want something done, do it yourself Comment: Obviously true, and doing it is usually very good for your self esteem. A surprising amount of work can be done this way, and experts are not always necessary. However, there is a risk of becoming overworked if you try to do everything yourself - we all need other people after all.

Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science.
How "SuperAger" Brains Are Different Than Everyone Else's
Researchers working with SuperAgers—people aged 80 and up with impeccable memory—reveal how their brains look decades younger. And compared to others their age, SuperAgers have nearly 90 percent fewer brain “tangles” linked to Alzheimer’s disease. The findings were published in the Journal of Neuroscience last week. First identified in 2007, the so-called cognitive SuperAgers displayed memories as sharp as people 20 to 30 years younger than them. In a preliminary study, researchers found that a particular region of their cortex was thicker than that of middle-aged participants. Now, in a more detailed study, a Northwestern University team led by Tamar Gefen used MRI scans to image the brains of 31 SuperAgers, and they also conducted postmortem investigations with five who donated their brains to science.

NASA Discovers Hidden Portals In Earth’s Magnetic Field
Our planet has come a long way in scientific breakthroughs and discoveries. Mainstream science is beginning to discover new concepts of reality that have the potential to change our perception about our planet and the extraterrestrial environment that surrounds it forever. Star gates, wormholes, and portals have been the subject of conspiracy theories and theoretical physics for decades, but that is all coming to an end as we continue to grow in our understanding about the true nature of our reality. In physics, a wormhole was a hypothetical feature of space time that would be a shortcut through space-time. We often wonder how extraterrestrials could travel so far and this could be one of many explanations.
