Our language abilities are enabled by a co-ordinated network of brain regions that have evolved to give humans a sophisticated ability to communicate. [bastian.]/Flickr

What brain regions control our language? And how do we know this?

When you read this text, certain regions in your brain begin working more than others. Advanced imaging allows scientists to map the brain networks responsible for understanding language.

Is anyone there? About consciousness and its disorders

Consciousness is one of the most puzzling phenomena in science. How does the electric and chemical activity in your brain produce your subjective experiences; the colour red or the taste of chocolate?

Brain connections predict how well you can pay attention

Particular parts of an individual's brain tend to work together on certain tasks. Researchers can look at these patterns of "functional connectivity" to predict traits – like the ability to pay attention.

Is there a moral centre in our brain?

There's no single region in the brain responsible for all moral decision making. But neuroscience research has shown specific brain regions are involved when we're faced with moral dilemmas.

AUDIO Q&A: Neuroeconomics and the answer to the ‘curse of choice’

We are faced with a myriad of choice in our lives - but an emerging body of work suggests the more choice we’re faced with, the more likely we’ll make a poor decision. The conundrum is called the “curse…
People are becoming more likely to believe that high-tech visualising techniques might allow us to see psychopathy in the actual physiology of the brain. JE Theriot/Flickr (resized)

Looking for psychopaths in all the wrong places: fMRI in court

In the latest instalment of our series Biology and Blame Micol Seigel poses some important questions about the assumptions behind the legal use of fMRI. Of the current uses of psychiatry in legal settings…

Dogs hear human happiness – it’s in his (or her) master’s voice

Dogs really are our best friends. A study published today in Current Biology shows not only do dogs and humans read emotions in each other’s “voices”, but both are more attuned to “happy” sounds. And the…
While a flinch, or a grimace may provide us with clues, ultimately we only know that someone’s in pain if they tell us. the italian voice/Flickr

Understanding pain: can the brain provide all the answers?
