New insight into personality psychology

Extraversion does not just explain differences between how people act at social events. How extraverted you are may influence how the brain makes choices - specifically whether you choose an immediate or delayed reward, according to a new study. The work is part of a growing body of research on the vital role of understanding personality in society.

New combination of neural imaging methods discovers brain's ability to adapt to injury

For the first time, scientists at Carnegie Mellon University's Center for Cognitive Brain Imaging (CCBI) have used a new combination of neural imaging methods to discover exactly how the human brain adapts to injury.

Preterm infants with slower growth have delayed development in the cerebral cortex

Preterm infants who grow more slowly as they approached what would have been their due dates also have slower development in an area of the brain called the cerebral cortex, report Canadian researchers in a new study published today in Science Translational Medicine.

Sp2 protein plays a key role in creation of neurons from stem cells

A protein known as Sp2 is key to the proper creation of neurons from stem cells, according to researchers at North Carolina State University. Understanding how this protein works could enable scientists to "program" stem cells for regeneration, which has implications for neural therapies.

Fifteen established scientists to receive NARSAD Distinguished Investigator Grants

The Brain & Behavior Research Foundation (formerly NARSAD, the National Alliance for Research on Schizophrenia and Depression) announced the latest recipients of its highly competitive NARSAD Distinguished Investigator Grants.

Bilingual older people reap neural rewards

Older bilingual people are faster than their monolingual peers in switching from one task to another, show researchers.

Scientists wrestle to understand why Huntington's can produce variable symptoms

Scientists have wrestled to understand why Huntington's disease, which is caused by a single gene mutation, can produce such variable symptoms. An authoritative review by a group of leading experts summarizes the progress relating cell loss in the striatum and cerebral cortex to symptom profile in Huntington's disease, suggesting a possible direction for developing targeted therapies.

Fluoxetine stimulates production of new neurons from L1-INP cells

The production of new neurons in the adult normal cortex in response to the antidepressant, fluoxetine, is reported in a study published online this week in Neuropsychopharmacology.

Women with menopausal transition experience cognitive difficulties

The memory problems that many women experience in their 40s and 50s as they approach and go through menopause are both real and appear to be most acute during the early period of post menopause. That is the conclusion of a study which appears today in the journal Menopause.

New insight into 22q11.2 deletion syndrome

Research out of the George Washington University (GW), published in the journal Proceedings of the National Academy of Sciences (PNAS), reveals another piece of the puzzle in a genetic developmental disorder that causes behavioral diseases such as autism.

MRI could serve as lumbar puncture proxy

Structural brain patterns on magnetic resonance imaging predict cerebrospinal fluid biomarker levels in patients with suspected Alzheimer’s disease or frontotemporal lobar degeneration, preliminary research suggests.

Electroconvulsive therapy releases opiate-like substances

Researchers used electricity on certain regions in the brain of a patient with chronic, severe facial pain to release an opiate-like substance that's considered one of the body's most powerful painkillers.

Prenatal brain development may be important influence on psychiatric risk later in life

Some brain changes that are found in adults with common gene variants linked to disorders such as Alzheimer's disease, schizophrenia, and autism can also be seen in the brain scans of newborns.

Study provides clear understanding of how the brain organizes visual input

Our eyes may be our window to the world, but how do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to put in order all the categories of objects and actions that we see. They have created the first interactive map of how the brain organizes these groupings.

Bipolar subtypes show neurobiologic differences

Results from a Taiwanese study show that there are significant neurobiologic differences between patients with bipolar I and II disorder.

Harvard scientists shed new light on olfactory feedback mechanism

More than a century after it was first identified, Harvard scientists are shedding new light on a little-understood neural feedback mechanism that may play a key role in how the olfactory system works in the brain.

Default mode network impaired in young adults at risk for psychosis

Young adults at genetic risk for psychosis show reduced activity in the default mode network area of the brain compared with those without such a family history, researchers report.

University of North Carolina awards 13th Perl prize to two NTNU-Trondheim scientists

The University of North Carolina at Chapel Hill has awarded the 13th Perl-UNC Neuroscience prize jointly to Edvard and May-Britt Moser at the Norwegian University of Science and Technology (NTNU-Trondheim) in Trondheim, Norway.

Paternal exposure to cocaine can impair gene expression and behavior in their offspring

Research from the Perelman School of Medicine at the University of Pennsylvania and Massachusetts General Hospital (MGH) reveals that sons of male rats exposed to cocaine are resistant to the rewarding effects of the drug, suggesting that cocaine-induced changes in physiology are passed down from father to son.

TUBB5 gene responsible for microcephaly: IMP study

Neurobiologists at the Research institute of Molecular Pathology (IMP) in Vienna have discovered one of the key genes required to make a brain. Mutations in this gene, called TUBB5, cause neurodevelopmental disease in children.
