Research may facilitate improved understanding of music perception in human nervous system

Music serves as a natural and non-invasive intervention for patients with severe neurological disorders to promote long-term memory, social interaction and communication. However, there is currently no plausible explanation of its neural basis for why and how music affects physical and psychosocial responses.

Researchers find the genetic mutation that is linked with changes in brain development

For decades, scientists have thought the faulty neural wiring that predisposes individuals to behavioral disorders like autism and psychiatric diseases like schizophrenia must occur during development. Even so, no one has ever shown that a risk gene for the disease actually disrupts brain development.

New neurosurgical procedure may prove helpful for patients with treatment-resistant depression

A new neurosurgical procedure may prove helpful for patients with treatment-resistant depression. Bilateral epidural prefrontal cortical stimulation (EpCS) was found generally safe and provided significant improvement of depressive symptoms in a small group of patients, according to lead researcher Ziad Nahas, M.D. at the Medical University of South Carolina. The data are reported in the on-line issue of Biological Psychiatry.

Scientists identify the first genetic mechanism that generates the cerebral cortex

The cerebral cortex, the largest and most complex component of the brain, is unique to mammals and alone has evolved human specializations. Although at first all stem cells in charge of building the cerebral cortex-the outermost layer of neurons commonly referred to as gray matter-are created equal, soon they irrevocably commit to forming specific cortical regions. But how the stem cells' destiny is determined has remained an open question.

Memory and sensory enhancement guide book

The great philosopher Socrates said, "The unexamined life is not worth living." Now, in his new book "Just Before..." (published by Trafford), author and NLP(TM) Wordsmythe Jeff Schoener presents readers with a way to examine their past and relive memories ranging from the simplest and most profound.

Learning new tasks causes changes in spontaneous brain activity patterns: Study

Spontaneous brain activity formerly thought to be "white noise" measurably changes after a person learns a new task, researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have shown.

Brain's mapping system uncovered

Through the power of Google Earth, you can travel the globe from the comfort of your computer screen, peering down on everything from above. But once you change your perspective - if you go into one of the buildings that you've looked down on - you have to upload a new map.

It is possible to communicate through power of thought alone: Study

New research from the University of Southampton has demonstrated that it is possible for communication from person to person through the power of thought alone.

Brain study of people with psychopathic personality disorder

The age-old debate of 'nature versus nurture', of how much our personality and behaviours are shaped by biology or our environment, is sharpening up as scientists' exploration of the human brain gets ever more sophisticated.

Non-invasive imaging technique can aid in diagnosing tinnitus

Complicating matters, physicians can rarely pinpoint the source of tinnitus, a chronic ringing of the head or ears that can be as quiet as a whisper or as loud as a jackhammer.

IRSF awards $2M for research into a cure for Rett syndrome

The International Rett Syndrome Foundation (IRSF) announced today that it is awarding grants totaling $2 million to support 18 innovative research projects in 2009. Each project will explore bold new ideas that have the potential to drive the field forward and speed the translation of research into treatments and a cure for Rett syndrome.

Alcoholism affects sleep even after long periods of abstinence for both men and women, says study

A study in the Oct.1 issue of the journal Sleep shows that long-term alcoholism affects sleep even after long periods of abstinence, and the pattern of this effect is similar in both men and women.

Manic-depression not a lifelong disorder

Bipolar disorder, or manic-depression, causes severe and unusual shifts in mood and energy, affecting a person's ability to perform everyday tasks. With symptoms often starting in early adulthood, bipolar disorder has been thought of traditionally as a lifelong disorder. Now, University of Missouri researchers have found evidence that nearly half of those diagnosed between the ages of 18 and 25 may outgrow the disorder by the time they reach 30.

Researchers measure the brain activity in infants

Do infants only start to crawl once they are physically able to see danger coming? Or is it that because they are more mobile, they develop the ability to sense looming danger? According to Ruud van der Weel and Audrey van der Meer, from the Norwegian University of Science and Technology in Trondheim, infants' ability to see whether an object is approaching on a direct collision course, and when it is likely to collide, develops around the time they become more mobile. Their findings have just been published online in the Springer journal Naturwissenschaften.

Jean-Pol Tassin honored with the ECNP Neuropsychopharmacology Award

The European College of Neuropsychopharmacology (ECNP) is pleased to announce Jean-Pol Tassin as the recipient of the 2009 ECNP Neuropsychopharmacology Award in Basic Science Research in recognition of his pioneering and innovative research into the neurochemical basis of substance addiction.

How the human brain processes incoming sensory signals amidst background noise

The brain never sits idle. Whether we are awake or asleep, watch TV or close our eyes, waves of spontaneous nerve signals wash through our brains. Researchers at the Salk Institute for Biological Studies studying visual attention have discovered a novel mechanism that explains how incoming sensory signals make themselves heard amidst the constant background rumblings so they can be reliably processed and passed on.

Integration of local motion signals allows for a larger global pattern motion

Researchers have long known of the brain's ability to learn based on visual motion input, and a recent study has uncovered more insight into where the learning occurs. The brain first perceives changes in visual input (local motion) in the primary visual cortex. The local motion signals are then integrated in the later visual processing stages and interpreted as global motion in the higher-level processes.

Neurodegenerative disorders are the second-leading cause of early-onset dementia, says report

Neurodegenerative disorders called frontotemporal dementias (FTD) are the second-leading cause of early-onset dementia in persons under age 65 and can emerge sometimes as early as age 20.

ICTs play a major role in the health care sector

Today the GridTalk project launches its 8th GridBriefing at the Enabling Grids for E-sciencE (EGEE) conference in Barcelona. The report covers how information and communication technologies (ICTs), particularly computing grids, are used in the health and biomedical sectors of European research. EGEE has supported this research community since the project's birth and it is the second largest user group after physics research.
