Human Intelligence Through Brain Scans

Researchers at Yale led a study that demonstrate fluid intelligence (defined by abstract reasoning) can be measured by the functional connectivity of 268 specific brain regions. Emily Finn, co-author of this study, said, “The more certain regions are talking to one another, the better you’re able to process information quickly and make inferences.” Mostly, fluid intelligence had to do with the connections between the frontal and parietal lobes. The stronger and swifter the communication between these two regions, the better one’s score in the abstract thinking test.Earlier, same researchers have demonstrated that a person’s brain activity appears to be as unique as his or her fingerprints. Using brain imaging data, researcher were able to identify individuals.

Experiment proves Reality does not exist until it is measured

Physicists at The Australian National University have conducted John Wheeler's delayed-choice thought experiment, which involves a moving object that is given the choice to act like a particle or a wave. Wheeler's experiment then asks — at which point does the object decide? Common sense says the object is either wave-like or particle-like, independent of how we measure it. But quantum physics predicts that whether you observe wave like behavior (interference) or particle behavior (no interference) depends only on how it is actually measured at the end of its journey.

Schizophrenia and the Teenage Brain: How Can Imaging Help?

Adolescence is a dangerous time for the onset of mental health problems. Advances in brain imaging are helping to picture how neural changes in these crucial years can lead to chronic debilitating mental illness.

Space Telescope Tech Miniaturized to Look into the Brain

Optical technologies previously used to look at the stars in the sky will be miniaturized to look inside the brain, and could lead to new treatments for neurological diseases. The technologies once used to make corrections to space telescopes, along with new lasers, will help answer a fundamental question, according to Prakash Kara, Ph.D., a researcher at the Medical University of South Carolina. Kara is part of a team at MUSC that was awarded a $4 million grant from the National Science Foundation through its Experimental Program to Stimulate Competitive Research (EPSCoR). The grant will fund collaborative research between MUSC and the University of Alabama at Birmingham to map changes in blood flow when specific neurons in the brain fire.

Dr. Prakash Kara says new equipment funded by the grant will dramatically improve researchers' ability to capture images deep in the brain. (Credit: Sarah Pack)

Paralyzed man drinks beer using his imagination

A man who is paralyzed from the neck down was able to drink from a bottle of beer by using his imagination. Erik Sorto, 34, has been paralyzed for the last 13 years, but was able to use a robotic arm controlled by his thoughts recently via two silicon chips in his brain, which were able to determine what his intentions were and then send those commands to a prosthetic arm on a table nearby.

Flying a jet via mind control

Jan Scheuermann, a quadriplegic and pioneering patient for an experimental Pentagon robotics program, continues to break ground in freeing the mind from the body. The 55-year-old mother of two in 2012 agreed to let surgeons implant electrodes on her brain to control a robotic arm. More recently, she flew an F-35 Joint Strike Fighter simulator using nothing but her thoughts, an official said.

X-ray vision with safe, visible light

According to Nature, scientists are honing methods to reassemble scattered light that passes through opaque objects to create a usable image on the other side, enabling see-through (super!) vision of objects.

Stroke Detecting Headset prototype from Samsung

Samsung’s Early Detection Sensor & Algorithm Package (EDSAP), developed by  Se-hoon Lim, is meant to detect early signs of stroke. A multiple sensor headset records electrical impulses in the brain, algorithms determine the likelihood of a stroke in one minute, and results are presented in a mobile app.  EDSAP can also analyze stress and sleep patterns, and potentially be used to monitor heart activity.  The company believes that the system can one day be built into one’s own glasses.

Playing action video games can boost learning

In the a new study, published in the Proceedings of the National Academy of Sciences, Bavelier and her team first used a pattern discrimination task to compare action video game players’ visual performance with that of individuals who do not play action video games.

The action-gamers outperformed the non-action gamers. The key to the action-gamers success, the researchers found, was that their brains used a better template for the task at hand.
