Bipolar disorder linked with gray matter loss

A new study indicates global bipolar disorder is connected to thinning of gray matter in the brain regions responsible for inhibition and emotion. This finding comes from the University of Oslo’s Faculty of Medicine.

Viewing brain images by new adaptive-optics technology

Scientists from Purdue University have developed a new adaptive-optics technology designed for brain research. The method, described as “multi-pupil adaptive optics”, helps with research into brain function.

Essential Science: Scientists are listening in on the brain

This week’s Essential Science takes a peak at research being carried out by different scientists to better understand the brain and brain activity. This involves the use of two novel processes, one based on sound and the other using light.

The new theory about memory formation surprises scientists

The rules of memory are 'beautifully' rewritten, according to new Riken-MIT research. The findings completely change earlier theories about the formation of memories in the brain.

Can human memory be improved with magnets?

The way we interpret the world is partly based on how we remember sounds and interpret these in our minds. New research into memory, building on this concept, suggests that memory might be improved through the use of magnets.

Scientists locate brain circuit that triggers pleasure response

Researchers have confirmed that the central amygdala, located deep within the brain, is connected with fear and responses to unpleasant events. The team has also detected a circuit within this structure that reacts to rewarding events.

When analyzing images big data beats the brain

When it comes to viewing and interpreting a series of images it seems that big data computing approaches are superior to the human brain. New findings have implications for the way images, such as those from CCTV, are interpreted.

Where does dyslexia begin in the brain?

Scientists think they have identified the point in the brain where dyslexia begins. It is hoped the insight gained will help to develop improved treatment options for those with the comprehension disorder.

Neuroscientists determine what makes consciousness

Neuroscientists have been studying the brain for the neural networks associated with consciousness. The identification of the brain network necessary for consciousness has come about through magnetic resonance imaging.

Classic video game console baffles neuroscientists

Researchers have used a classic video game console to try to analyse neural networks. Since looking at the networks in the brain is a highly complex process, the researchers hoped studying an old Atari 2600 system would prove simpler. It didn’t.

Mediterranean diet beneficially affects brain volume

New research indicates that the Mediterranean diet leads to a positive impact on brain health. This is based upon brain volume being maintained at a higher rate.

How stress on the brain triggers heart attacks

Scientists have confirmed the link between stress, a region of the brain and heart attacks. The research shows why stress can sometimes lead to a heart attack.

Rates of depression increase among teenage girls

Depression, at least in the U.S., is increasing among teens, with the largest increase seen with teenage girls. This is based on a new assessment of medical case history over a ten year period.

Brain ‘re-wires’ after pregnancy

When a woman becomes a mother it is a life-changing experience. While this is obvious in many ways, new research indicates that the brain undergoes changes and the changes persist for many years.

Visualizing the effect of stress on the brain

What happens to the brain when a person undergoes a stressful event? What are the longer-term effects of a condition like Post-Traumatic Stress Disorder? These questions have been recently examined by scientists.

New brain implant for ALS patients

Amsterdam - People who have Amyotropic Lateral Sclerosis (ALS-Lou Gehrig’s) lose muscle function and eventually require continual care. A new implant has been developed by University Medical Center researchers that could help those with the condition.

Parts of the brain fall asleep and wake up again

When people are awake the brain’s activity moves through states described as waves. This new observation seems to relate to how much attention is paid at a given point in time and may explain attention lapses.

Brain area where depression occurs is detected

Feeling low? Scientists now know where in the brain depression is most strongly associated with. The region is associated with reward and it also interacts with a second region of the brain that stores memories.

Stretchy optical fibers used to assess for signs of diseases

A special type of optical fiber, made from a hydrogel, has been developed. This rubber-like device can detect diseases early and send an alert signal.

Animal study shows how omega-3s help to reduce stroke damage

Working with mice, researchers have shown that the effects of stroke triggered brain damage can be reduced following injections of omega-3 fatty acids.

Ultrasound used to 'jump-start' a 25-year-old man's brain

Bradley Crehan was hit by a car after walking out of a bar in Santa Monica, California, last February. The 25-year-old's head slammed to the ground, causing a severe brain injury.

New imaging method tracks neurological diseases

Medical researchers have devised a new imaging method to track genetic markers in the human brain. Abnormalities with these genes are indicators of potential neurodegenerative diseases like Alzheimer’s.

Scientists find high level of zinc can increase seizure risk

Austin - Zinc might be an important nutrient, but it can raise the risk of seizures when it gets into the brain, according to new research Texas A&M scientists.

Promising drug dissolves blood clots

Saint Petersburg - A promising new development drug lowers the risk of strokes by dissolving away blood clots (thrombolysis) in a targeted manner.

Waking and sleeping states need a ‘chemical cocktail’

The act of falling asleep and then waking up is more complex, and slightly different, than previously thought, according to new research. The process involves a chemical cocktail.

New AI app for the iPhone gives you an 'intelligent memory'

A new app is seeking to bring artificial intelligence and machine learning to the iPhone, giving you an "intelligent memory" inside your smartphone. Snips has modelled the way humans learn to create an app that sorts and links all your data.

How macrophages repair brain bleeding

The breaking of blood vessels can be the cause of significant risk, such as the triggering of strokes. One way the body addresses these is through macrophages and understanding this can help with stroke prevention.

Revealed: What LSD does to the brain

Brain imaging has provided researchers with the first ever look about how LSD causes its profound effects on human consciousness.

NFL acknowledges link between brain disease and football

Washington - The connection between American Football and brain trauma has featured in a number of studies. However, until now, football authorities have never acknowledged the connection. This has changed following an inquiry.

This prehistoric puppy tells the story of canine evolution

Frozen in Siberian permafrost, this puppy died more than 12,000 years ago and is remarkably well-preserved. In fact, it's so well-preserved that scientists have performed an autopsy, in the hopes that it will solve the mysteries of canine evolution.
