Physical exercise is critical to brain health.
The results astonishingly suggest that Alzheimer’s effects on the brain could be reversed.
German researchers reprogramed brain cells to investigate how place memories are formed.
Neurogenesis fully stops after the age of thirteen, researchers suggest.
In a dark way, these findings are quite soothing.
It’s really, really good for you.
A groundbreaking study suggests the human brain works fundamentally different than science thought.
Sleep is as mysterious as it is vital for our wellbeing.
Science is getting closer to a computer that mimics the human brain.
A 28-year old who has been paralyzed for more than a decade following a spinal cord injury has become the first person to be able to “feel” physical sensations, through a special prosthetic developed by DARPA – the Defense Advanced Research Projects Agency, a US agency responsible for the development of emerging technologies, mostly for military purposes. The prosthetic hand is connected directly
The human brain is one of the biggest and most intriguing mysteries scientists are tackling. It’s an incredibly active, bustling place that keeps us going and effectively makes us the people we are. There are about 100 billion neurons processing and transmitting information through electrical and chemical signals and to make things even more complicated, each of these neurons has about 10,000 different connections to neighboring brain cells.
The human brain is often described as the most beautiful organism in the Universe. We say this because of the beautiful things the mind, sustained by the brain, can create and imagine. Greg Dunn earned his PhD in Neuroscience at the University of Pennsylvania in 2011, but while his colleagues are fiddling with microscopes to unravel the inner workings of brain cells, he works with a paintbrush to magnify neurons on a canvas. His work shows a brain whose beauty transcends romanticism and awes in its raw form.
For a while, the general consensus was that long term memories are stored in synapses. A new UCLA research topples this paradigm after experiments made on snails suggests that synapses aren’t that crucial storing memories as previously believed, but only facilitate the transfer of information someplace else, most likely in the nucleus of the neurons themselves – though this has yet
Oh, boy. This week’s freaky science story comes from the University of Rochester Medical Center in New York where researchers grafted mouse pups with human glial cells. Within one year, half the brain cells of the by now adult mice were human. A study made last year by the same team suggests that mice whose brains contain human glial cells
A Chinese woman has shocked doctors when it was revealed that she reached 24 years without having a cerebellum. It is not the first time a person was living fine without having a cerebellum, but she entered an extremely select group, which only features 9 other people. The woman checked in at the Chinese PLA General Hospital of Jinan Military Area Command
Scientists have “reprogrammed” skin cells to act as neurons and then successfully implanted them into the brain of mice. After 6 months, the new nerve tissue was fully functional and there was no sign of rejection or other side effects.
Researchers have erased and then reactivated memories in rats, profoundly impacting the animals’ reaction to past events. This is the first study ever to demonstrate the ability to selectively erase and then reactivate a memory by stimulating nerves in the brain at frequencies that strengthen synapses, the connection between neurons. The Eternal Sunshine of the Spotless Mind Quite possibly Jim Carrey’s
If you’re trying to hold on to old memories, then some new, fresh brain cells may be the last thing you need – a new research published in Science suggests that newly formed neurons in the hippocampus (an area in the brain responsible for memory formation) could remove previously stored information. This is perhaps the reason why childhood memories are
A new study which involved the analysis of over 1.000 brain scans confirmed what many intuitively believed for a long time: men and women’s brains are hard wired differently. Maps of neural circuitry showed that on average women’s brains were highly connected across the left and right hemispheres, while men had better connections between the front and back areas of
Trying to better understand how memories are stored inside a human brain, researchers from the University of Pennsylvania and Freiburg University used a video game in which people navigate through a virtual town delivering objects to specific locations; they found that brain cells add a geo-tag with spatial information to some memories, and this spacial information is activated immediately before
