EPFL scientists reveal that the brain is not as compact as we thought

Using an innovative method, EPFL scientists show that the brain is not as compact as we have thought all along. To study the fine structure of the brain, including its connections between neurons, the synapses, scientists must use electron microscopes. However, the tissue must first be fixed to prepare it for this high magnification imaging method.

DISC-1: schizophrenia's "Rosetta Stone" gene? An interview with Professor Kevin Fox

The DISC-1 gene has been studied intensively over the years because people with mutations in DISC1 have a high likelihood of mental illness. DISC-1 was known to be associated with schizophrenia, bipolar disorder, major clinical depression and autism.

McGill researchers identify brain structures involved in delayed gratification

Researchers at McGill have clearly identified, for the first time, the specific parts of the brain involved in decisions that call for delayed gratification. In a paper recently published in the European Journal of Neuroscience, they demonstrated that the hippocampus (associated with memory) and the nucleus accumbens (associated with pleasure) work together in making critical decisions of this type, where time plays a role.

DBS may aid cortical plasticity in Parkinson’s patients

Deep-brain stimulation of the subthalamic nucleus may help to restore long-term potentiation-like plasticity in the motor cortex of patients with Parkinson’s disease, a study shows.

Research finding could help reveal how the human brain learns complex motor skills

Like top musicians, songbirds train from a young age to weed out errors and trim variability from their songs, ultimately becoming consistent and reliable performers. But as with human musicians, even the best are not machines. To learn and improve, the songbird brain needs to shake up its tried-and-true patterns with a healthy dose of creative experimentation. Until now, no one has found a specific mechanism by which this could occur.

Study reveals how brain work leads to physical fatigue

Do you ever notice how stress and mental frustration can affect your physical abilities? When you are worried about something at work, do you find yourself more exhausted at the end of the day? This phenomenon is a result of the activation of a specific area of the brain when we attempt to participate in both physical and mental tasks simultaneously.

Study sheds new light on the brain’s learning capacity

How do you get to Carnegie Hall? New research on the brain's capacity to learn suggests there's more to it than the adage that "practise makes perfect." A music-training study by scientists at the Montreal Neurological Institute and Hospital -The Neuro, at McGill University and colleagues in Germany found evidence to distinguish the parts of the brain that account for individual talent from the parts that are activated through training.

Study could pave way for more targeted treatments for individuals with brain disorders

Like Duke Ellington's 1931 jazz standard, the human brain improvises while its rhythm section keeps up a steady beat. But when it comes to taking on intellectually challenging tasks, groups of neurons tune in to one another for a fraction of a second and harmonize, then go back to improvising, according to new research led by UC Berkeley.

New research may aid in treatment of vision problems like lazy eye

If you have two working eyes, you are live streaming two images of the world into your brain. Your brain combines the two to produce a view of the world that appears as though you had a single eye -- like the Cyclops from Greek mythology.

Twenty Radboud researchers receive Veni grant as part of Innovational Research Incentives Scheme

Twenty young and promising researchers from Nijmegen - eleven from Radboud University and nine from Radboudumc - are each to receive up to 250,000. NWO (The Netherlands Organisation for Scientific Research) is awarding the Veni grant as part of the Innovational Research Incentives Scheme.

Emotionally unstable people have different brain structure

We all vary in how often we become happy, sad or angry, and also in how strongly these emotions are expressed. This variability is a part of our personality and can be seen as a positive aspect that increases diversity in society. However, there are people that find it so difficult to regulate their emotions that it has a serious impact on their work, family and social life. These individuals may be given an emotional instability diagnosis such as borderline personality disorder or antisocial personality disorder.

Adults born very premature display socially withdrawn personality

New research indicates that adults born very premature are more likely to be socially withdrawn and display signs of autism.

Researchers examine brain networks involved in PTSD and TBI

Posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI) can have devastating consequences. Both are associated with high rates of disability and suicide, and although they are separate conditions, they commonly co-occur. For example, a soldier who has developed PTSD as a result of a traumatic experience may have also sustained a brain injury during that experience.

Expectations shape babies' brains

Infants can use their expectations about the world to rapidly shape their developing brains, researchers have found.

Transcranial magnetic stimulation holds promise for tinnitus patients

In the largest U.S. clinical trial of its kind funded by the Veterans Affairs Rehabilitation Research and Development Service, researchers at the VA Portland Medical Center and Oregon Health & Science University found that transcranial magnetic stimulation significantly improved tinnitus symptoms for more than half of study participants.

Neuronal activity in the brain's prefrontal cortex is nuanced and complex, new study finds

Results of a new study reported this week by David Moorman of the University of Massachusetts Amherst and Gary Aston-Jones of Rutgers University suggest that adjusting behavior based on previous events involves an unexpected mix of neurons working together in the brain's prefrontal cortex.

New findings point toward potential blood test to detect schizophrenia

High blood levels of a growth factor known to enable new blood vessel development and brain cell protection correlate with a smaller size of brain areas key to complex thought, emotion and behavior in patients with schizophrenia, researchers report in the journal Molecular Psychiatry.

Researchers identify gene that underlies thinking skills

An international team of researchers, including investigators from the University of Mississippi Medical Center, has identified a gene that underlies healthy information processing -- a first step on a complicated road to understand cognitive aging and age-related diseases, such as Alzheimer's disease.

Gene therapy provides life-long protection to photoreceptor cells in animal model of retinitis pigmentosa

A collaboration between scientists in the UK and the USA has shown that gene therapy can give life-long protection to the light-sensitive photoreceptor cells responsible for colour vision in a mouse model of the most common inherited eye disorder.

Studies using MRI techniques can reveal brain connectivity differences in people with ASD

Studies using magnetic resonance imaging (MRI) techniques are beginning to reveal differences in brain connectivity--the ways that different parts of the brain are connected to each other and work together--in people with autism spectrum disorders (ASD), reports a review in the Harvard Review of Psychiatry.
