Healthy teen screen use at night

Both in Europe and the US, more than 90% of adolescents have their faces buried in screens before bed. Often, this comes at a cost to sleep. Frequent screen users are much more likely to report falling asleep later, sleeping less, and waking during the night. Such difficulties are linked not only to poorer academic [...]

How an Internet Overload Could Lead to Digital Dementia

Emily Joyce was at a yoga retreat when she realised her memory was not what it used to be. "I was with a group of friends and we were trying to remember the name of a restaurant," says Joyce. "None of us had our phones and it took us so long to remember it." For [...]

The 13 Ways to Anti-Age Your Brain

The risk of dementia doubles every five years after the age of 65 in Australia. And whereas before little was  known about this debilitating disease, we now have "some good ideas as to what may be the contributing mechanisms", says Professor Perminder Sachdev, co-director of the Centre for Healthy Brain Ageing (CHeBA), UNSW. While there's no [...]

Men and Women Process Emotions Differently

This Is the Equation for Happiness

Researchers at University College London were able to create an equation that could accurately predict the happiness of over 18,000 people, according to a new study. First, the researchers had 26 participants complete decisionmaking tasks in which their choices either led to monetary gains or losses. The researchers used fMRI imaging to measure their brain [...]

Don’t Take Notes with a Laptop

Technology offers innovative tools that are shaping educational experiences for students, often in positive and dynamic ways. The research by Mueller and Oppenheimer serves as a reminder, however, that even when technology allows us to do more in less time, it does not always foster learning. Learning involves more than the receipt and the regurgitation [...]

Is The Science Of Brain Imaging Overrated?

Hardly a week passes without some sensational news about brain scans unleashing yet another secret of our cognitive faculties. Very recently I stumbled upon the news that according to recent research neuroscientists can tell, depending on your brain responses, whether you and your significant one will still be together in a few years: “You might hide it from [...]

Neuroplasticity Primer

With subjective experience new cells are incorporated into the brain and new circuits are created, altered, strengthened or weakened. The static view of the brain has been disproven and it is now known that the brain is very active—constantly changing connections and growing circuits, thought-by-thought, minute-by-minute and day-by-day. Many different brain mechanisms alter neuronal connections—in [...]

Pornography addiction leads to same brain activity as alcoholism or drug abuse

People who are addicted to pornography show similar brain activity to alcoholics or drug addicts, a study has revealed. MRI scans of test subjects who admitted to compulsive pornography use showed that the reward centres of the brain reacted to seeing explicit material in the same way as an alcoholic’s might on seeing a drinks [...]
