National trial: EEG brain tests help patients overcome depression

A new study found that measuring electrical activity in the brain can help predict a patient’s response to an antidepressant.

New findings explain how melatonin promotes sleep

Researchers have discovered how melatonin suppresses neurons in the brain that keeps you awake and alert. These findings could lead to new therapies for those who suffer from insomnia.

How REM and non-REM sleep may work together to help us solve problems

Sleep is known to be important for creative thinking, but exactly how it helps and what role each sleep stage — REM and non-REM — plays remains unclear. A team of researchers have now developed a theory to explain how the interleaving of REM and non-…

How can we help children with brain injuries transition back to school?

Children with brain injuries face significant challenges when transitioning from hospital or home to school where they face issues such as lack of educator understanding and catching up with missed work. Leading researchers in the field of pediatric br…

Magnetic stimulation dampens brain response to drug cues in addiction

In a study investigating the use of transcranial magnetic stimulation (TMS) for drug addiction, researchers are the first to demonstrate that the noninvasive brain stimulation technique can dampen brain activity in response to drug cues in chronic alco…

Why some people resist authority

Control aversion — the urge to rebel against control over one’s decisions — can be explained by connectivity between two regions of the brain as well as behavioral measures of distrust and lack of understanding.

New hope for patients with depression and anxiety

There is a strong link between depression and anxiety disorders and autoimmune thyroiditis (AIT), a chronic thyroid condition affecting approximately 10 percent of the population. Scientists have now demonstrated that special treatment could help many …

Where hominid brains are concerned, size doesn’t matter

Researchers pieced together traces of Homo naledi’s brain shape from an extraordinary collection of skull fragments and partial crania, from at least five adult individuals. One of these bore a very clear imprint of the convolutions on the surface of t…

How the brain decides to make an effort

From deciding to quit hitting the snooze button and get out of bed in the morning to opting to switch off the TV and prepare for sleep at night, the mind weighs the costs versus benefits of each choice we make. A new study reveals the mechanics of how …

Biologists ‘transfer’ a memory through RNA injection

Biologists report they have transferred a memory from one marine snail to another, creating an artificial memory, by injecting RNA from one to another. This research could lead to new ways to treat traumatic memories with RNA — perhaps a traumatic mem…
