Life without music – study looks at brain with amusia

For most people listening to music or playing an instrument is a great way to relax, unwind, have fun, and express themselves. But not everybody is able to perceive, appreciate or memorize music, to sing or to dance. Monica is one such person, and to her, any kind of music is just a bunch of noise that makes her head ache and feel stressed.

How your brain puts the “where” and “when” in memories

It's not RAM.

Each memory relies on three critical elements, those being the “what,” “where” and “when” building blocks. Neuroscientists from MIT have identified a brain circuit — connecting the hippocampus and a region of the cortex known as entorhinal cortex — that handles the “when” and “where” components.

A language that sounds like birdsong, whistled Turkish, uses both brain hemispheres

Whistled Turkish Involves Both Cerebral Hemispheres in Its Processing. Image: Capital Wired

One of the most peculiar languages in the world, whistled Turkish, is challenging the long-standing idea that the left brain hemisphere is solely responsible for processing language and extracting meaning. Any language, be it spoken, written or signed is processed in the left hemisphere, but whistled languages are processed equally by both sides of the brain. It’s a striking discovery that suggests people devoid of left hemisphere processing abilities, following a stroke for instance, can still communicate using their right hemisphere. Just whistle.

Crater wall collapse causes lava explosion in Hawaii [with video]


A crater wall collapse in a Hawaiian volcano has triggered a powerful lava explosion. The Kilauea explosion spread lava and debris around it, in a spectacular display which was caught on camera by the USGS. Material was thrown 280 feet (85 meters) up into the air. Janet Babb, a geologist with the USGS, compared the blast to popping a champagne

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.

Kept in the dark: half of Alzheimer’s diagnoses aren’t disclosed by doctors

Alzheimer's diagnosis

For its annual report, the The Alzheimer’s Association in the US claims that more than half of all reported early Alzheimer’s diagnoses aren’t disclosed to the patient by doctors. This is a situation reminiscent of the 1960s and 1970s when cancer diagnoses were rarely disclosed to patients as the disease was generally seen as incurable. Like in the case of the long-gone cancer stigma, doctors may be doing more harm than good. They don’t want patients to lose hope, but being kept in the dark as to their suffering can be equally bad, if not worse.

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

Storing info in computers frees up memory in the brain, helping us learn new things better

brain storage

Widespread use of computers is said to make people dumber or more prone to forgetfulness. It’s true, while we’re less inclined to memorize things such as poems or mathematical formulas, this doesn’t necessarily make it a bad thing. A study made by US psychologists found that when people save information on their computers or phones, this frees up cognitive resources

How the brain transforms bad experiences into long-lasting and unpleasant memories

Unpleasant memories are a lot easier to form than regular ones. Image: Silence of the Lambs.

Really bad experiences, like going through a particularly stressful or frighting situation, are a lot easier to remember than the things we do a day to day basis, or even those special pleasant experiences. That’s because we’re sort of evolutionary geared to remember those particularly nasty experiences so that we might avoid these in the future. A collaborative effort between New York
