Extra-virgin olive oil might prevent Alzheimer’s and protect your brain

It’s really, really good for you.

Dendrites generate electrical spikes too — human brain computing capacity might be 100 times larger than thought

A groundbreaking study suggests the human brain works fundamentally different than science thought.

We sleep to forget things, new study finds

Sleep is as mysterious as it is vital for our wellbeing.

IBM Scientists make phase-changing Artificial Neurons to mimic the Computer Power of Human Brain

Science is getting closer to a computer that mimics the human brain.

Paralyzed man becomes the first person to feel physical sensations through a prosthetic hand directly connected to his 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 Brain Wikipedia – Scientists Launch Open-Access Neuron Database

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.

Stunning Neurons on Canvas Painted by a Neuroscientist

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.

Long-term memory isn’t stored in synapses, meaning it could be restored even when struck by Alzheimer’s

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

Mice with half human brains are smarter, some healthier

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

Chinese woman completely lacks a cerebellum

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 successfully implant new neurons into the brain

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.

Scientists erase memory (and then reactivate it) in rats

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

New brain cells erase old memories

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

Men and women’s brains are hard wired differently, study shows

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

Memories Are Geo-tagged With Spatial Information

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

Migraines linked with abnormal brain arteries

We’re all swept from time to time by the occasional migraine, and rest assured you don’t want anyone around you when that time comes. Some people, however, suffer from migraines more often than others in what’s recently been classified as chronic migraines. It’s still unclear what causes them. Some studies point to dilation of blood vessels in the head, it’s even

Scientists discover molecular trigger for itch

An itch is a sensation that causes the desire or reflex to scratch. Researchers have long tried to characterize itch, but in its typical annoying fashion, the sensation resisted any such attempts. For a very long time, the itch has been thought of as a low-level form of pain, but now, a new study conducted on mice suggests that it

Flipping a single “molecular switch” makes an old mouse brain young

A single molecular switch can make the transition between the active, malleable brain of an adolescent and the mature, stable brain of an adult; yep, a single gene can turn us back to the childlike curiosity we exhibit as adolescents. Researchers have known for quite a while that adolescent brains are typically more malleable (or plastic) than adult ones, allowing

Obama funds brain mapping, interesting questions arise

This week, the Obama administration has announced plans to pursue a 10-year, $3 billion research effort aimed at mapping the human brain in “its entirety”. The project, called the Brain Activity Map, is designed to help scientists better understand how the ~100 billion neurons interact in our brains. Initially, the announcement was met with applause, as  the study could prove

Slime can navigate using external memory, despite having no brain – a precursor to the nervous system?

Scientists at University of Sydney have been studying for the past few years one of the most peculiar events in nature. It seems that a living slime, no less, no more, is capable of reading information and remembering its past “steps” acting on some sort of external memory, this despite the fact that it has no brain, not even one single
