Pick up a newspaper any day of the week and you’ll likely see articles breathlessly describing our progress towards unlocking the mysteries of the human brain. If the 1990s were the decade of the human genome, marked by the Human Genome Project (the world’s largest collaborative biological project), this is the era of the human brain.
With projects such as BRAIN and the Human Brain Project now well underway, and billions of dollars of private funding advancing neurological research and discovery, the future of brain science is within sight.
When he launched the BRAIN initiative in the United States, President Barack Obama said: “As humans, we can identify galaxies light years away, we can study particles smaller than an atom, but we still haven’t unlocked the mystery of the three pounds of matter between our ears.” Unlocking those mysteries will be transformative for society. Which is terrific, and terrifying. Consider the possibilities:

Mice suffering chronic pain undergo a change in brain circuitry that makes them less willing to work for a reward, even though they still want it.
Chronic pain is among the most abundant of all medical afflictions in the developed world. It differs from a short-term episode of pain not only in its duration, but also in triggering in its sufferers a psychic exhaustion best described by the question, “Why bother?”
A new study in mice, conducted by investigators at the Stanford University School of Medicine, has identified a set of changes in key parts of the brain that may explain chronic pain’s capacity to stifle motivation. The discovery could lead to entirely new classes of treatment for this damaging psychological consequence of chronic pain. Read More
Heated debate over a high-profile project of the European Commission to simulate the entire brain on a supercomputer – a long needed “paradigm-shift” in neuroscience, or an over-hyped, over-funded boondoggle destined to fail, at the expense of other smaller, cheaper, less sexy researches?
Researchers say European commission-funded initiative to simulate human brain suffers from ‘substantial failures’

The world’s largest project to unravel the mysteries of the human brain has been thrown into crisis with more than 100 leading researchers threatening to boycott the effort amid accusations of mismanagement and fears that it is doomed to failure.

So accustomed are we to metaphors related to taste that when we hear a kind smile described as “sweet,” or a resentful comment as “bitter,” we most likely don’t even think of those words as metaphors. But while it may seem to our ears that “sweet” by any other name means the same thing, new research shows that taste-related words actually engage the emotional centers of the brain more than literal words with the same meaning.
Researchers from Princeton University and the Free University of Berlin report in the Journal of Cognitive Neuroscience the first study to experimentally show that the brain processes these everyday metaphors differently than literal language. In the study, participants read 37 sentences that included common metaphors based on taste while the researchers recorded their brain activity. Each taste-related word was then swapped with a literal counterpart so that, for instance, “She looked at him sweetly” became “She looked at him kindly.”
Researchers from Princeton University and the Free University of Berlin found that taste-related metaphors such as “sweet” actually engage the emotional centers of the brain more than literal words such as “kind” that have the same meaning. If metaphors in general elicit a similar emotional response, that could mean that figurative language presents a “rhetorical advantage” when communicating with others.

Every day it seems like we feel hundreds of different emotions – each nuanced and specific to the physical and social situations we find ourselves in.
According to science, it’s not that complicated by a long shot. A new study says we’re really only capable of four “basic” emotions: happy, sad, afraid/surprised, and angry/disgusted.
But much like the “mother sauces” of cooking allow you to make pretty much any kind of food under the sun, these four “mother emotions” meld together in myriad ways in our brains to create our layered emotional stews.
Robert Plutchik’s famous “wheel of emotions” shows just some of the well known emotional layers.
In this post we’ll take a close look at each of the four emotions, how they form in the brain and the way they can motivate us to surprising actions. Read More

Learning a second language could improve reading and intelligence skills
Learning a second language can have a positive effect on the brain, even if it is taken up in adulthood, a University of Edinburgh study suggests.
Researchers found that reading, verbal fluency and intelligence were improved in a study of 262 people tested either aged 11 or in their seventies.
A previous study suggested that being bilingual could delay the onset of dementia by several years. The study is published in Annals of Neurology.
The big question in this study was whether learning a new language improved cognitive functions or whether individuals with better cognitive abilities were more likely to become bilingual. Dr Thomas Bak, from the Centre for Cognitive Ageing and Cognitive Epidemiology at the University of Edinburgh, said he believed he had found the answer.
Using data from intelligence tests on 262 Edinburgh-born individuals at the age of 11, the study looked at how their cognitive abilities had changed when they were tested again in their seventies. Read More
