Discovery of essential mechanism for maintenance of myelin's structure

In a new study, researchers at the Montreal Neurological Institute (MNI), McGill University, and the University of Montreal have discovered an essential mechanism for the maintenance of the normal structure of myelin, the protective covering that insulates and supports nerve cells (neurons).

The interaction between genes and behavior

Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.

Brain stimulation improves dexterity

Applying electrical stimulation to the scalp and the underlying motor regions of the brain could make you more skilled at delicate tasks. Research published today in the open access journal BMC Neuroscience shows that a non-invasive brain-stimulation technique, transcranial direct current stimulation (tDCS), is able to improve the use of a person's non-dominant hand.

Study looks at rare condition known as phonagnosia

The first known case of someone born without the ability to recognise voices has been reported in a paper by UCL (University College London) researchers, in a study of a rare condition known as phonagnosia. The UCL team are calling for other people to come forward if they think they have also grown up with the condition.

Why some people have a better head for languages

Learning a second language is usually difficult and often when we speak it we cannot disguise our origin or accent. However, there are important differences between individuals with regard to the degree to which a second language is mastered, even for people who have lived in a bilingual environment since childhood.
