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.

Chromosomes play active role in animal cell division

Canadian and British researchers have discovered that chromosomes play an active role in animal cell division. This occurs at a precise stage - cytokinesis - when the cell splits into two new daughter cells.

Researchers examine limits of human hearing

Are wind farms harmful to humans? Some believe so, others refute this; this controversial topic makes emotions run high. To give the debate more objectivity, an international team of experts dealt with the fundamentals of hearing in the lower limit range of the audible frequency range (i.e. infrasound), but also in the upper limit range (i.e. ultrasound).

Shape of the cerebral cortex strongly correlates with genetic ancestry

Researchers at the University of California, San Diego and the School of Medicine have found that the three-dimensional shape of the cerebral cortex - the wrinkled outer layer of the brain controlling many functions of thinking and sensation - strongly correlates with ancestral background.

Retrosplenial cortex serves as 'conjunction junction' for brain's navigation function

Ever wake at night needing a drink of water and then find your way to the kitchen in the dark without stubbing your toe?

Decreased connectivity between network-specific brain regions linked to cognitive deficit in MS

An estimated 2.3 million individuals are living with multiple sclerosis (MS) worldwide. Approximately half of all individuals with MS experience changes in cognition such as impaired concentration, attention, memory, and judgment. The underlying brain basis for these deleterious effects has been largely elusive.

MIT researchers reveal key brainwave changes among patients receiving nitrous oxide

Nitrous oxide, commonly known as "laughing gas," has been used in anesthesiology practice since the 1800s, but the way it works to create altered states is not well understood. In a study published this week in Clinical Neurophysiology, MIT researchers reveal some key brainwave changes among patients receiving the drug.

Computer model could help develop better strategies for treating early-childhood visual disorders

When newborn babies open their eyes for the first time, they already possess nerve cells specialized in particular stimuli in the visual cortex of their brains - but these nerve cells are not systematically linked with each other.

Brain-imaging studies may help predict promiscuity, problem drinking in young adults

A pair of brain-imaging studies suggest researchers may be able to predict how likely young adults are to develop problem drinking or engage in risky sexual behavior in response to stress.

Cognitive behavioural therapy can change brain function of people with Tourette syndrome

In addition to its effect on chronic tics, cognitive behavioural therapy (CBT) can change the brain function of people with Tourette syndrome.

Neuromodulator norepinephrine has direct action on auditory processing of complex signals

For neuroscientists studying the intricate mechanisms of hearing in the brain's auditory cortex, a major question has been how a listener can focus in a noisy environment, and how neurochemicals help neurons convey as much embedded information as possible for the rest of the brain to act on.

Scientists redraw traditional brain map of language comprehension

For 140 years, scientists' understanding of language comprehension in the brain came from individuals with stroke. Based on language impairments caused by stroke, scientists believed a single area of the brain -- a hotdog shaped section in the temporal lobe of the left hemisphere called Wernicke's region -- was the center of language comprehension.

10-week reading intervention improves brain activity in autistic children

Ten weeks of intensive reading intervention for children with autism spectrum disorder was enough to strengthen the activity of loosely connected areas of their brains that work together to comprehend reading, University of Alabama at Birmingham researchers have found.
