Study uncovers why almost winning is just as good for some gamblers

A new study led by the University of Exeter and Swansea University has pinpointed the changes in the brain that lead gamblers to react in the same way to near-misses as they do to winning.

The research shows that near-misses are underpinned by increases in the brain’s electrical activity, particularly in the theta frequency range – known to be involved in processing win and loss outcomes.

They found that these increases in theta are linked to both how severe someone’s gambling history is and how susceptible they might be to developing a future gambling problem. (more…)

Sleep helps the brain consolidate what we’ve learned, but scientists have struggled to determine what goes on in the brain to make that happen for different kinds of learned tasks. In a new study, researchers pinpoint the brainwave frequencies and brain region associated with sleep-enhanced learning of a sequential finger tapping task akin to typing, or playing piano.

PROVIDENCE, R.I. [Brown University] — You take your piano lesson, you go to sleep and when you wake up your fingers are better able to play that beautiful sequence of notes. How does sleep make that difference? A new study helps to explain what happens in your brain during those fateful, restful hours when motor learning takes hold. (more…)
