Words On The Brain: A Semantic Map of the Cortex

by Neuroskeptic in Neuroskeptic_Discover

In a new Nature paper, Berkely neuroscientists Alexander G. Huth and colleagues present a 'semantic atlas' of the human brain. Huth et al. have mapped which brain areas respond to words, according to the semantics (meanings) of each word. It turns out that these maps are highly similar across individuals - which could have implications for 'mind reading' technology.



Huth et al. recorded brain activity with fMRI while seven volunteers listened to over two hours of audio narrative (taken fr... Read more »

The 'anti-neuroinflammatory activity' of oxytocin

by Paul Whiteley in Questioning Answers

Whilst the package inserts of the various drugs that modern medicine has at its disposal provides important information on potential mode of action, there is a growing realisation that drugs generally have quite a few more molecular targets than are perhaps listed. Take for example the quite commonly used (in some parts of the world anyway) compound called melatonin  that in some instances can provide almost miraculous relief when it comes to sleeping issues under certain circumstances. A d........ Read more »

Don’t retweet if you want to remember

by Dr. Jekyll in Lunatic Laboratories

The whole of human intelligence, right at your fingertips. Sure it might not make the layman an engineer or physicist, but if we want to learn about a particular topic the internet can give us that information. But you better hold on tight before you lose it. New research finds retweeting or otherwise sharing information creates a “cognitive overload” that interferes with learning and retaining what you’ve just seen.

Cuckoldary is rare in humans!

by Farid Pazhoohi in Epistemophil

Human behavioral scientists argue that extra-pair copulation is adaptive in human females, as through extra-pair copulation, women can acquire good genes from other potential mates. This is suggested because it is found that women experience greater sexual attraction to particular extra-pair men, but not their own partners, during their highest peak of fertility (Gangestad & […]...

Hunting For The Signatures of Cancer

Signatures of Mutational Processes Extracted from the Mutational Catalogs of 21 Breast Cancer Genomes. Credit:http://dx.doi.org/10.1016/j.celrep.2012.12.008Cancer is the second leading cause of death worldwide, with approximately 14 million new cases and 8.2 million cancer related deaths each year (Source: WHO). A family history of cancer typically increases a person's risk of developing the disease, yet most cancer cases have no family history at all. This suggests that a combination of both ge........

Phubbing, more FOMO, blonde jokes, and what holds our  attention?

Why organisations should encourage their staff to become friends

by BPS Research Digest in BPS Research Digest

They say you should never mix business and pleasure but in reality many of us find that we become friends with the people who we work with. No wonder, when you consider the hours spent together and the deep bonds formed through collaboration and sharing the highs and lows of the job.A new study in Personnel Psychology is among the first to examine the effects on job performance of having more "multiplex relationships" – colleagues you work with directly who are also your friends outside of wor........

Organophosphate exposure and ADHD?

MERS-CoV and antiviral singling: role of orf4b and M protein

by thelonevirologist in Virology Tidbits

Coronaviruses (CoV) are positive sense RNA viruses with a genome size of 29-32 kb with four genera (Alpha-, Beta-, Gamma- and Delta CoV) belonging to the family of the Coronaviridae within the order of Nidovirales, with the Betacoronaviruses further divided into four lineages (A-D).

Most CoV identified until now are causing severe disease only in animals including agricultural important animals such as chicken, cattle, and pigs. To date only six human CoV (HCoV) have been identified, namely ........ Read more »

Sophie Deneve and the efficient neural code

Phylo.io a new interactive way of visualising and comparing trees

by Christophe Dessimoz in Open Reading Frame

The paper introducing our new tree visualisation tool Phylo.io was just published in MBE.

Yet another tool to display trees, you might say, and indeed, so it is. But for all the tools that have been developed over the years, there are very few that scale to large trees, make it easy to compare trees side-by-side, and simply run in a browser on any computer or mobile device.

To fill this gap, we created Phylo.io.

Breathing Bordeaux is entirely different from drinking it!

by Rosin Cerate in Rosin Cerate

It was the summer of 1882, and grape farmers in the Médoc region of southwest France (north of Bordeaux, on the Atlantic coast) had a problem.Schoolchildren (or university students, or just anyone travelling the roads along which the grapevines grew, depending on what source you're reading) were pilfering their grapes. To try and ward them off, some farmers decided to dissolve some slaked lime and copper sulfate in water and spray it on their grapevines closest to the roads. The idea was... Read more »

Portrait of a linguistic shirker

by Ingrid Piller in Language on the Move








I recently pointed out that the widespread belief that migrants refuse to learn the language of their new country does not stack up against the realities of adult language learning. I summarized the research that shows that adult language learning is complex and difficult and rarely an all-out success; to blame migrants for their failure to learn a new language (well) is adding insult to injury.

The Neural Precursors of Spontaneous Thoughts

by Neuroskeptic in Neuroskeptic_Discover

Back in 2013, I wondered if we would ever discover the neural basis of spontaneous thoughts. Why, I asked, do certain ideas just "pop" into our minds at particular times? Now a new paper published in Neuroimage, Canadian neuroscientists Melissa Ellamil and colleagues reports on the neural basis of spontaneous thoughts.



Ellamil et al. recruited a group of 18 volunteers, all of whom were highly experienced practitioners of mindfulness meditation. These individuals were selected, the authors... Read more »

What parents of children with autism expect from their child's therapists

by Paul Whiteley in Questioning Answers

"Parents ultimately wanted therapists to produce positive outcomes for their children and were willing to sacrifice other desired qualities, as long as the therapy program was effective."and"The SLPs [Speech-Language Pathologists] expressed strong support for evidence-based practice (EBP) and indicated that they thought parents expected their children would be provided with evidence-based interventions."Those quotes come from two papers recently published in the same journal; the first........

Addiction, it’s in your genes… maybe

by Dr. Jekyll in Lunatic Laboratories

Why does one person who tries cocaine get addicted, while another might use it and then leave it alone? Why do some people who kick a drug habit manage to stay clean, while others relapse? And why do some families seem more prone to addiction than others? According to a new study, the road to answering these questions may have a lot to do with specific genetic factors that vary from individual to individual.

Measuring happiness on social media

by Dr. Jekyll in Lunatic Laboratories

Happiness. It’s something we all strive for, but how do we measure it — as a country? A global community? Not so surprisingly, researchers are turning to social media to answer these questions and more. In a newly published study, computer scientists used two years of Twitter data to measure users’ life satisfaction, a component of happiness.

Rafting Ants Have Designated Stations

by Elizabeth Preston in Inkfish



Sometimes at the climax of a Star Trek episode, the captain would yell out "Battle stations!" and send the crew scurrying frantically through the corridors. It wasn't really clear what those battle stations were. Presumably, crew members headed to posts they'd been previously assigned, and this let the whole ship react to the crisis efficiently.

Certain ants respond to a crisis by binding their bodies together into floating rafts. And like the Star Trek crew, they seem to have designat........ Read more »
