There are very few people living with chronic pain who gleefully swallow a handful of pills and skip happily off for the day feeling chipper and bright as a button. For the most part, people living with chronic pain don’t seem to enjoy the need to take medications – I’ve heard some say they’re worried about “not being able to tell whether I’m doing damage” when they can’t feel their pain, others say they don’t think medications are very helpf........

A new study shows that while video game players (VGPs) exhibit more efficient visual attention abilities, they are also much more likely to use navigation strategies that rely on the brain’s reward system (the caudate nucleus) and not the brain’s spatial memory system (the hippocampus). Past research has shown that people who use caudate nucleus-dependent navigation strategies have decreased grey matter and lower functional brain activity in the hippocampus.... Read more »

Neuroscientists might need to rethink much of what's known about the amygdala, a small brain region that's been the focus of a lot of research. That's according to a new paper just published in Scientific Reports: fMRI measurements of amygdala activation are confounded by stimulus correlated signal fluctuation in nearby veins draining distant brain regions.
The amygdala is believed to be involved in emotion, especially negative emotions such as fear. Much of the evidence for this comes fr... Read more »
