I just happened across this video from National Geographic showing how methamphetamines affect the brain, both in the short term and the long term. It gives an informative, concise look into what’s happening in the brain to make the drug so very addictive–and how that addiction can ruin the sense of joy that everyday life [...]

It’s common wisdom that women become emotionally unhinged when it’s their “time of the month,” right? Supposedly, we get weepy, angry, and just generally difficult whenever our periods come along. Is it true? For some women, sure, at least on occasion. Others aren’t as affected. This emotional instability has long been associated with hormonal changes [...]

I happened across this video of Stephen Wiltshire, an autistic man whose ability to remember incredible detail and draw it with near perfection is extraordinary. If he flies in a helicopter over a city just once, he can recreate the city perfectly in a drawing. The buildings have the right number of columns and windows. [...]

Do you ever read about a study that’s received a million dollar grant and think, “Who would spend a million dollars to study THAT? And what kind of scientists would want to spend their time on it?” That’s what I first thought when I heard about research on sea slug brains. I couldn’t figure out [...]

Perhaps you’ve heard that we humans are special in the animal world because our brains are so very, very big for our size. Not true, as it turns out. Sure, they’re big compared to a bird brain or a dog brain, but in the primate world our brain size is pretty unremarkable–at least according to this [...]

Viewing television and playing video games each are associated with increased subsequent attention problems in childhood.

There was a deeply jarring article in the New York Times earlier this week that told the story of an extended Colombian family with unprecedented rates of early-onset Alzheimer’s. How their incredible suffering might hold the key for discovering a cure for Alzheimer’s is the subject of the article. Young people in this family grow [...]

I’d like to share a great educational tool from the Alzheimer’s Association website. It’s a 16-slide Brain Tour that shows the differences between a healthy brain and one with Alzheimer’s. The tour has fantastic roll-over visuals that make it easy to understand what changes in the brain of an Alzheimer’s patient and how it affects [...]

I just found out that more than half of babies born in developed countries today will live to be more than 100 years old. That’s a lot of centenarians. Apparently, with each passing year humankind (in rich countries, at least) gains an average of 3 months of extra life expectancy, thanks to medical advances. As [...]

Multiple studies have shown that Posit Science training programs produce many benefits for healthy adults by improving cognitive performance. There is also great interest in the science community for using our products to address cognitive decline in clinical populations. The goal of brain plasticity based training programs is to re-normalizing brain function through rigorous and [...]
