Researchers at Northwestern University have used a non-invasive form of magnetic brain stimulation to improve the memory of older adults. After just five short sessions the older adults scored as well as a younger cohort on a variety of memory tasks...

In a breakthrough study, researchers have managed to restore some brain function in pigs as long as four hours after death. Using a system that pumps preserving chemicals through the brain's circulatory system, the team not only staved off cell death but actually restored some functions like synaptic activity. The astounding discovery raises some ethical questions and may spark new debate
Though it is already administered in off-label doses at clinics across the US for its rapid anti-depressant effects and, significantly, was approved in nasal spray form by the FDA last month, there remains a lot to learn about ketamine and its close chemical relatives. A new study has shed more light on how it can stave off depressive symptoms, with experiments on mice revealing how it rep
From treating depression to curtailing the effects of Parkinson's disease to awakening patients in a vegetative state, stimulating the brain with electrical currents holds all kind of potential. One very promising branch of this research centers on arresting cognitive decline by boosting memory and learning, and a string of recent studies have uncovered its exciting potential in this regar
There's plenty to be said about the negative health effects of jet lag, but could a journey through the clouds have a silver lining? New research out of Northwestern University suggests that indeed it might, uncovering evidence that disruptions to circadian clocks can have a protective effect on neurons, opening up some interesting new pathways for research into degenerative brain diseases
A rigorous new study has examined the large-scale brain activity of a number of human subjects while sleeping, presenting one of the most detailed investigations into sleep phases conducted to date. The study suggests that instead of the traditional four sleep stages we generally understand the brain moves through, there are in fact at least 19 different identifiable brain patterns transit
Deep brain stimulation (DBS), where electrodes are used to deliver mild electric currents to targeted regions of the brain, is showing promise as a treatment for a range of conditions, including Alzheimer's, Parkinson's and depression. A new study exploring the lattermost of these has returned "absolutely sensational" results, with the reduction of depressive symptoms being not only fast-a
An important part of the human brain has to work harder to actively forget a memory than it does to remember it, according to the results of a newly-published study. The research is a step towards understanding how and why the brain is able to discard an experience, and could one day lead to a treatment designed to remove painful memories...

In a first-of-its-kind study from researchers at the University of North Carolina (UNC) School of Medicine, a new kind of non-invasive electrical brain stimulation has been trialed in patients with major depression. The results show this new technique to be extraordinarily promising in reducing depressive symptoms, with larger trials set to explore this novel treatment in greater detail...
For the first time scientists have demonstrated how the brain washes away toxic proteins during a specific phase of deep sleep. The study builds on a growing body of evidence suggesting chronic sleep disruption could play a role in the onset of Alzheimer's and dementia...
