Scientists have discovered that ultrasound directed to a specific areas of the brain can enhance sensory awareness and perception in the brain.

Most people are familiar with the use of ultrasound scanners as devices that utilise high frequency sound waves to create images of internal organs. This technology has now been adapted by researchers at Virginia Tech Carilion Research Institute to affect brain performance.

The near-death experience reported by cardiac arrest survivors worldwide may be grounded in science, according to research at the University of Michigan.

Previously, it was not believed that the brain could be active after death, but now it appears that there is a burst of superconsicous activity for about 30 seconds AFTER its blood flow has stopped. Some scientists are saying that this is proof that the near-death experience is ‘all in the brain,’ but others aren’t so sure.

A U-M study showed shortly after clinical death, in which the heart stops beating and blood stops flowing to the brain, rats display brain activity patterns characteristic of conscious perception.

Archeologists usually investigate ancient sites, but what if neurologists could dig into the brain’s past and uncover the history of past experiences? Recent brain studies have revealed that spontaneous waves of neuronal activity in the brain bear the imprints of earlier events for at least 24 hours after the experience has taken place. This means that close encounter witnesses’ brains will contain a signature of their experience, and it would be possible to determine from that whether it was a physical event or a nightmare. This would be an enormous and important step forward in close encounter research.
