It’s not quantity but quality that matters when it comes to how much sleep strengthens our memories. A growing body of research is finding that specific stages of sleep shape particular types of learning in the brain. Whether for children napping or for older adults catching z’s at night, we all rely on sleep to […]
Musings on Consciousness, Technology and Bioethics: Q&A with Adrian Owen
“Surely, if we are going to make judgments about whether people should be kept or alive or allowed to die after serious brain injury, it’s better if the people themselves are involved in that decision-making process, rather than others – doctors, relatives, etc. – being entirely responsible for making that decision for them.” Breakthroughs in […]
Boost Your Brain with Aerobic Exergames
Q&A with Cay Anderson-Hanley “While exercise does not appear to be a cure-all, it is one of the strongest tools that we individually can enlist in our fight against cognitive decline and diseases of many types.” Playing video games that double as exercise can reap mental benefits above and beyond traditional exercise. In a recent […]
Navigation and Recall: Why There Are Some Places We Just Can’t Forget
Even for those of us navigationally challenged, we may have vivid memories of exactly where we once saw a bad accident or a deer on the side of the road. These negative experiences boost our recall of places, according to new research. As a result, the very places we may want to forget are the […]
Visual Recognition Study that Led to New fMRI Analysis Technique
Breakthroughs in cognitive neuroscience: Highlighting influential research from the past 20 years This series explores influential papers in cognitive neuroscience, as measured by the number of times they are cited each year. The papers featured are a sampling of many important works in the field over the past 20 years. This is the fourth in […]
Meditation Training Helps Smokers Quit Smoking – Even If They Didn’t Plan To
Curbing a smoking habit is a tough task, but a new tool could be in the arsenal: meditation. A new study found that a meditation training regiment reduced smoking among participants, even those who did not intend to kick the habit. “Individuals at risk for substance abuse, including smoking, typically have deficits in self-control,” says […]
How Testosterone Affects Risk-Taking in Adolescent Boys and Girls
Adolescents are infamous for engaging in more risky behavior as they mature from children to adults. This transition is notable for many changes, including a surge in testosterone for both boys and girls. The changing levels of testosterone, combined with the size of a frontal region of the brain, help to explain risk-taking in adolescence, […]
Stress Hormone Hinders Memory Recall
Most of us can recall a time when our mind blanked in an exam. Ironically, that vivid memory is of a time when we just couldn’t remember something. Part of the explanation for this contradiction is the stress hormone cortisol. While increased levels of cortisol boost the formation of memories, they can hinder their recall. […]
Framing Our Experiences: New Study Reveals Attention at Neuron Level
Q&A with Ron Mangun Two people sitting at a sports bar watching a game may notice very different things around them. While one may see the couple next to him arguing, the other may see a small fire starting in the kitchen. How they direct their attention, whether consciously or not, could lead to important […]
