Consolidating memories in sleep

In a unique new study, scientists planted tiny microelectrodes into the brains of two people to see how we store memories. They found that neurons that were active when the person did a task (in this case, playing a Simon-like game) “replayed” the steps of that task during sleep—helping to store the memory for a […]

A Doctor’s Self-Experiment

Dr. Nico Dosenbach often prescribes CIMT (constraint-induced movement therapy) to his patients with disabled arms or hands. The idea is to keep the stronger arm still, so that the patient has to use their other one. To have a better idea of how and why it works, he decided to do an experiment on himself: […]

Plasticity in Pregnancy

Recent research shows that the brain is particularly plastic—that is, able to reshape itself—during pregnancy and the postpartum period. Among other changes, the pregnant brain tends to show a reduction in grey matter. This “loss” might be good: it may free up resources as the brain develops the skills needed to care for an infant. […]

The Brains of “Super-Agers”

A new study from researchers in Australia compared the brains of cognitively healthy “super-agers” (aged 95+) to the brains of people in their 70s. They found that the super-agers had stronger connectivity between the left and right sides of the brain. It’s another step in uncovering the secret of successful aging. More on “People […]

Tutoring versus Brain Training?

Dear Parents, the reality is . . . waiting for your child to “grow out of” learning, reading, or attention difficulties is not really an option. Learning struggles rarely go away with time. On the contrary, waiting and hoping a problem will go away without appropriate intervention will only lead to frustration, poor grades, low […]
