Repairing stroke-damaged rat brains

Researchers at Lund University in Sweden have succeeded in restoring mobility and sensation of touch in stroke-afflicted rats by reprogramming human skin cells to become nerve cells, which were then transplanted into the rats' brains. The study has now been... Continue Reading →

Chilling concussed cells shows promise for full recovery

In the future, treating a concussion could be as simple as cooling the brain. That's according to research conducted by University of Wisconsin-Madison engineers, whose findings support the treatment approach at the cellular level. "There are currently no effective medical... Continue Reading →

Where in the brain does creativity come from? Evidence from jazz musicians

According to a popular view, creativity is a product of the brain's right hemisphere -- innovative people are considered "right-brain thinkers" while "left-brain thinkers" are thought to be analytical and logical. Neuroscientists who are skeptical of this idea have argued... Continue Reading →

Worldwide scientific collaboration unveils genetic architecture of gray matter

The cerebral cortex is the relatively thin, folded, outer "gray matter" layer of the brain crucial for thinking, information processing, memory, and attention. Not much has been revealed about the genetic underpinnings that influence the size of the cortex's surface... Continue Reading →

New research reveals that scents alter how memories are processed in the brain

In a new paper published in Learning and Memory, researchers from Boston University's Center for Systems Neuroscience reveal just how much power scents have in triggering the memory of past experiences--and the potential for odor to be used as a tool to treat... Continue Reading →

Exercise activates memory neural networks in older adults

How quickly do we experience the benefits of exercise? A new University of Maryland study of healthy older adults shows that just one session of exercise increased activation in the brain circuits associated with memory - including the hippocampus -... Continue Reading →

Scientists monitor brains replaying memories in real time

In a study of epilepsy patients, researchers at the National Institutes of Health monitored the electrical activity of thousands of individual brain cells, called neurons, as patients took memory tests. They found that the firing patterns of the cells that... Continue Reading →

Bilingualism acts as a cognitive reserve factor against dementia

The conclusions of a study carried out by VĂ­ctor Costumero, as the first author, Marco Calabria and Albert Costa (died in 2018), members of the Speech Production and Bilingualism (SPB) group at the Cognition and Brain Center (CBC) of the... Continue Reading →

How loneliness affects end-of-life experiences

In a study of Americans over age 50 years who died between 2004 and 2014, individuals who were characterized as lonely based on survey results were burdened by more symptoms and received more intense end-of-life care compared with non-lonely people.... Continue Reading →
