Scientists decode brain waves to eavesdrop on what we hear

February 1, 2012 (TSR) - Neuroscientists may one day be able to hear the imagined speech of a patient unable to speak due to stroke or paralysis, according to University of California, Berkeley researchers. These scientists have succeeded in decoding electrical activity in the brain’s temporal lobe — the seat of the auditory system — as a person listens to [...]

U.S. Army Looks to Counteract Nightmares With Digital Dreams

Many soldiers are broken and lost their faith in their life's purpose because of their experiences in Iraq and Afghanistan. They all see the wars meaningless and does not serve any purpose. They kill the innocent upon orders. Is it any wonder why they come home with nightmares? It is called guilty conscience.

Oct. 27, 2011 (Wired/TSR) –  A soldier tries to sleep. But he is not safe in his dreams. Jolted awake by a nightmare, the combat veteran fumbles in the dark for his 3-D glasses. He puts them on. Around him are the faces of people whom he trusts. They fight the darkness with him. The [...]

YOU are hereby ordered to spontaneous TRUTH-telling!

YOU have the right to remain truthful.

Sept 12, 2011 (New Scientist/TSR) – YOU will tell the truth. Applying a magnetic field to the brain seems to hamper our ability to tell lies. Lying is thought to involve inhibiting our normal propensity to truth-telling, so Talis Bachmann’s team at the University of Tartu in Estonia reasoned that dampening brain activity in the dorsolateral [...]

TRAINING THE BRAIN: Early light refines the brain’s circuitry for vision

Light and sight: connected at the beginning Because the retinal layer of rods and cones is not connected early in mice, neuroscientists had no reason to suspect that light helps develop neural connections for vision. David Berson, right, with Jordan Renna, has shown that photosensitive cells he discovered a decade ago are connected and do help with neural development. Credit: Mike Cohea/Brown University

Creatures are not born hardwired to see. Instead, they depend on electrical activity in the retina to refine the complex circuits that process visual information. Two new studies from Brown University in different species using different techniques show how nascent animal brains use light to wire up or construct their central vision system.   Any [...]

Political views are reflected in brain structure

025471-political-brain

We all know that people at opposite ends of the political spectrum often really can’t see eye to eye. Now, a new report published online on April 7th in Current Biology, a Cell Press publication, reveals that those differences in political orientation are tied to differences in the very structures of our brains. Individuals who call [...]

How to Train Your Own Brain

BOSTON, Massachusettes, USA. November 23, 2010 (MIT) - Technology might not be advanced enough yet to let people read someone else’s mind, but researchers are at least inching closer to helping people to read and control their own. In a study presented last week at the Society for Neuroscience meeting in San Diego, scientists used a combination [...]

Electrical brain stimulation improves math skills

brain-booster

Are you bad at sums? Get muddled at the market? If so, you could benefit from a machine that improves your mathematical abilities. It’s not such a strange suggestion. Stimulating a particular area of the brain, it turns out, can improve numeracy for at least six months. In 2007, Roi Cohen Kadosh at the University of Oxford [...]

Quantum ‘weirdness’ used by plants, animals

Birds like the European robin have an internal compass which appears to make use of a phenomenon called quantum entanglement.

Bird navigation, plant photosynthesis and the human sense of smell all represent ways living things appear to exploit the oddities of quantum physics, scientists are finding. Quantum mechanics is the branch of physics dealing with the strange behaviour of very tiny things like elementary particles and atoms, and is extremely different from the physics that [...]
