brain

Ever wondered what your brain sounds like on the inside? Trinity College philosophy professor Dan Lloyd has created a program that orchestrates our brainwaves. Scanning brains on an MRI, Lloyd can watch as certain areas of the brain light up and then assign different frequencies to the areas of the brain used, correlating the intensity of usage with volume. The results are bizarrely beautiful.

Wish you had a photographic memory? Well, Encyclopedia Brown, drugs may amp your brain up to that point soon. A group of Spanish scientists claim to have singled out a protein that can extend the life of visual memory significantly. When the production of the protein was boosted in mice, the rodents' visual memory retention increased, from about an hour to almost 2 months.

Scientists have achieved a new milestone in brain imaging: we have seen a memory in the process of being formed. Using brain cells from a lowly sea slug, which actually makes a good model for our brains, images were captured of proteins forming between the neurons. These proteins distinguish the memory as a long-term one rather than short-term, as the proteins solidify the memory in the neurons. This process had been suspected but not visualized until now.

Neuroscientists are already able to read some basic thoughts, like whether an individual test subject is looking at a picture of a cat or an image with a specific left or right orientation. They can even read pictures that you're simply imagining in your mind's eye. Even leaders in the field are shocked by how far we've come in our ability to peer into people's minds. Will brain scans of the future be able to tell if a person is lying or telling the truth?

"The simple headline here is that Google is making us smarter," says Gary Small of the Semel Institute for Neuroscience and Human Behavior at the University of California at Los Angeles. Thank you, Dr. Small. And thank you, Internet, for not only helping me dig up this information but also juicing up my brain while I looked for it. Small recently published results showing that searching the Internet does for the brains of older folks what doing bench presses does for chest muscles.

A neuroscientist carves up brains to investigate the presence of unique brain cells found only in humans, primates, elephants and a handful of marine mammals -- species that are characterized by large brains, a long childhood spent learning from their elders, and sophisticated social interaction, reports Smithsonian.

In his Caltech lab, John Allman slices off the thinnest slivers of an elephant's brain, looking for the presence of von Economo neurons -- and possibly a glimpse into the evolution of human behavior.

Intuitively, you probably already know that music is a powerful memory trigger. Just shuffle through your favorite playlists and you’ll probably land on a few nostalgic tunes that take you back to high school, your first love, or that perfect summer vacation. Now a recent study proves that music, memory, and emotion are linked in the brain, and the research could have implications for the therapy of Alzheimer’s patients.

Financial institutions aren't the only banks hurting these days. Brain banks—repositories for donated brains—are running low on fresh noggins for research, said a group of scientists from various institutions in the United Kingdom this week. Get past the ewww factor (remember nasty Halloween games and that creep Frankenstein?), and fresh brains are essential for researching neurological and psychiatric disorders, such as Alzheimer's, autism, Parkinson's, and schizophrenia.

I challenge you: Name one fact you still remember from the last test for which you crammed.

Anyone? Any fact?

If you’re often paralyzed with worry and can’t utter a word in social situations, stop faulting your mother – your lack of intercalated (ITC) neurons is to blame. Neuroscientists from Rutgers University in New York shed a light on anxiety last week, when they published a paper that pinpoints which brain cells are responsible for fear.

The effects of smoking have been well documented. Heart disease and emphysema, lung cancer and yellow teeth; the list seems to go on forever. Well, add one more to that list: enhanced memory. A new study conducted at King’s College in London indicates that the addictive and highly toxic chemical nicotine might improve memory and stave off the onset of dementia.

The human brain is still largely an unsolved mystery. We only marginally understand how it works and are even less able to predict how it will behave in certain situations. One of the most frustrating of those situations is the coma. Anecdotes abound of people in comas who unexpectedly wake from them, much to their doctors' surprise. But what if doctors could get ahead of that surprise with a predictor of whether or not a patient will regain consciousness? A team of Belgian scientists have proposed just such a clue.

In my Science Confirms the Obvious post today, I discussed the first psychological proof (so say the authors) that humans can indeed experience emotions without immediately knowing why. We do this, they say, because we evolved that way. True, scientists love that explanation, but here its quite intriguing.

Say youre walking through the woods and encounter a grizzly bear. You see it and freeze that instant—even before your stomach drops with fear.

Alan Gevins and his team at SAM Technology in San Francisco are nearing the end of a large study analyzing the effects of various drugs on cognitive performance. An editor at Technology Review recently visited their offices, and downed a stiff cocktail, to experience their work first-hand.
