The brain stores memories relative to time and place of origin

By - August 18, 2015 2 Pictures

Where and when you form new memories affects where they are stored in the brain's hippocampus, which is the memory center in our brain, researchers at Ohio State University found in a new study. They saw evidence that a particular part of the hippocampus stores memories relative to time over durations of at least a month and space over distances of up to 30 km (18.6 mi).

Mice brainpower boosted with alteration of a single gene

By - August 17, 2015 1 Picture

"Ignorance is bliss," so the old saying goes, but who wouldn't give their brainpower a boost if they had the chance? By altering a single gene to inhibit the activity of an enzyme called phosphodiesterase (PDE4B), researchers have given mice the opportunity to see what an increase in intelligence is like. While many people would welcome such a treatment, the scientists say their research could lead to new treatments for those with cognitive disorders and age-related cognitive decline.

Color-changing polymer to indicate severity of hits to the head

By - August 17, 2015 1 Picture

A head trauma can be difficult to diagnose and destroy a life years after the event. Being able to tell immediately if the force someone has suffered is sufficient to result in a traumatic brain injury can make all the difference in limiting the damage. A team from the University of Pennsylvania has developed a material that could one day be incorporated into headgear to instantly gauge the severity of blows and provide a clearly visible indication of injury.

Putting a price tag on brainpower

By - August 17, 2015 1 Picture

If you offer someone "a penny for their thoughts," how good a deal might you be getting? A study conducted at the University of Leicester has sought to shed some light on the value of our brainpower, finding a single penny to be worth to precisely three hours, seven minutes and 30 seconds worth of thinking.

Sleeping on your side appears to cut the risk of neurological disorders

By - August 13, 2015 1 Picture

New research suggests that sleeping on your side could help cut the chances of developing some neurological disorders, including Alzheimer's and Parkinson's. Compared to sleeping on one's back or stomach, sleeping on one's side appears to allow the brain to more efficiently remove waste chemicals that may contribute to the development of such conditions.

Nicotine-gobbling enzyme could help smokers quit

By - August 6, 2015 1 Picture

Nicotine replacement therapy, such as pills, gum and patches, can make the road to quitting smoking a little less rocky, but these aren't always effective and a tremendous amount of discipline still plays the major role. A team of US-based researchers has now uncovered an enzyme found in nature they say could greatly improve on the effectiveness of smoking cessation aids, by devouring nicotine in smokers before it can deliver its "reward" to the brain.

New therapy to help addicts put memories of meth use behind them

By - August 5, 2015 1 Picture

Even after a lengthy period of abstinence, putting lingering memories of methamphetamine use to rest is a difficult and often impossible task for former users. Therapies are available to help people stay clean, but for many the lure remains irresistible with incredibly high relapse rates of more than 90 percent, according to the National Institute on Drug Abuse. But a research team is hoping to help addicts stay away from the devastating drug for good by developing a way to safely erase drug-associated memories.

Imaging tool lets scientists look inside brain at nanoscale resolution

By - August 1, 2015 5 Pictures

The human brain contains more synapses than there are galaxies in the observable universe (to put a number on it, there are perhaps 100 trillion synapses versus 100 billion galaxies), and now scientists can see them all – individually. A new imaging tool promises to open the door to all sorts of new insights about the brain and how it works. The tool can generate images at a nanoscale resolution, which is small enough to see all cellular objects and many of their sub-cellular components (so for the biology-literate, that's stuff like neurons and the synapses that permit them to fire, plus axons, dendrites, glia, mitochondria, blood vessel cells, and so on).

Implantable device hits targeted brain cells with light and drugs when triggered remotely

By - July 17, 2015 1 Picture

The field of optogenetics where individual brains cells are made to behave differently when exposed to light has wide-ranging potential. It may one day be used to reverse acquired blindness, alter pain thresholds and even hit the rest button on our biological clocks. With one eye on this emerging area of neuroscience, scientists have developed a device the width of a human hair that can be planted in the brain to deliver light or drugs only where needed, offering better targeted treatments and reduced side effects.
