Brain stimulation improves learning in people with schizophrenia

Very mild electrical brain stimulation could be used as a treatment for people with schizophrenia, say researchers.

Changes in attention, Gestalt perception linked to healthy aging

When looking at a picture of many trees, young people will tend to say: "This is a forest". However, the older we get, the more likely we are to notice a single tree before seeing the forest. This suggests that the speed at which the brain processes the bigger picture is slower in older people.

Neuroscience 2011 to explore latest advances in brain research

The Society for Neuroscience's Annual Meeting, Neuroscience 2011, Nov. 12-16 at the Washington Convention Center. The event will include more than 16,000 study abstracts on new discoveries in aging, stress, mental illness, learning, disease, and more.

Visual perception can be contaminated by recent memories

Taking a trip down memory lane while you are driving could land you in a roadside ditch, new research indicates. Vanderbilt University psychologists have found that our visual perception can be contaminated by memories of what we have recently seen, impairing our ability to properly understand and act on what we are currently seeing.

USC researcher maps human brain that generates empathy

According to a new study from USC, even failing to possess a full complement of limbs will not stop your brain from understanding what it is like for someone else to experience pain in one of them. It may, however, change the way your brain does so.

Meditation appears to change brain anatomy: Study

Two years ago, researchers at UCLA found that specific regions in the brains of long-term meditators were larger and had more gray matter than the brains of individuals in a control group. This suggested that meditation may indeed be good for all of us since, alas, our brains shrink naturally with age.

Study explains how 'positivity effect' leads to successful aging

Whether we choose to accept or fight it, the fact is that we will all age, but will we do so successfully? Aging successfully has been linked with the "positivity effect", a biased tendency towards and preference for positive, emotionally gratifying experiences.

Study demonstrates how unconscious brain continues to process information

Brain damage can cause significant changes in behaviour, such as loss of cognitive skills, but also reveals much about how the nervous system deals with consciousness. New findings reported in the July 2011 issue of Elsevier's Cortex demonstrate how the unconscious brain continues to process information even when the conscious brain is incapacitated.

New method to study neuronal activity in the deepest layers of the cortex

Visual and tactile objects in our surroundings are translated into a perception by complex interactions of neurons in the cortex. The principles underlying spatial and temporal organization of neuronal activity during decision-making and object perception are not all understood yet.

Researchers identify biomarker for familial risk of autism

Siblings of people with autism show a similar pattern of brain activity to that seen in people with autism when looking at emotional facial expressions. The University of Cambridge researchers identified the reduced activity in a part of the brain associated with empathy and argue it may be a 'biomarker' for a familial risk of autism.

American Tinnitus Association awards $10,000 to Wayne State University student

Na Zhu, a Wayne State University College of Engineering student, has received the 2011 American Tinnitus Association Student Research Grant Program award. The program financially supports scientific studies that investigate and aim to find a cure for tinnitus.

Insights into how brain can preserve memory and prevent forgetting

As any student who's had to study for multiple exams can tell you, trying to learn two different sets of facts one after another is challenging. As you study for the physics exam, almost inevitably some of the information for the history exam is forgotten.

Study links OBEs with neural instability and errors in body representation

Although out-of-body experiences (OBEs) are typically associated with migraine, epilepsy and psychopathology, they are quite common in healthy and psychologically normal individuals as well. However, they are poorly understood.

'Plasticity' genes make it harder to form new memories about unfamiliar topics

Scientists have shed light on why it is easier to learn about things related to what we already know than it is to learn about unfamiliar things, according to a new study.

Infants treated with certain HIV medication more likely to experience adrenal dysfunction

Infants of human immunodeficiency virus 1 (HIV-1) infected mothers who were treated before and after birth with the protease inhibitor lopinavir-ritonavir were more likely to experience adrenal dysfunction, including life-threatening adrenal insufficiency in premature infants, compared with a zidovudine-based regimen, according to a preliminary report in the July 6 issue of JAMA.

Men better than women at visuo-spatial and auditory-spatial tasks

Differences in male and female behaviour are often subject to study. Women are known to be more verbally fluent, have better manual dexterity and are better at noticing things (like a new haircut). Men on the other hand often take less time parking their cars and have less trouble than women in navigating in a new city.

Nicotine receptors play crucial role in social interaction

If you think nicotine receptors are only important to smokers trying to kick the tobacco habit, think again. New research published in the FASEB Journal (http://www.fasebj.org) suggests that these receptors also play an important role in social interaction and the ability to choose between competing motivations.

Early musical interventions may benefit children with dyslexia having difficulties in learning to read

Children with dyslexia often find it difficult to count the number of syllables in spoken words or to determine whether words rhyme. These subtle difficulties are seen across languages with different writing systems and they indicate that the dyslexic brain has trouble processing the way that sounds in spoken language are structured.

Emotional empathy linked to physiological responses to angry faces

Egocentric, self-centred, and insensitive to the needs of others: these social problems often arise in people with severe traumatic brain injury (TBI) and have been attributed in part to a loss of emotional empathy, the capacity to recognise and understand the emotions of other people.

Study shows how binge drinking could cause serious brain damage in young adults

It's considered a rite of passage among young people - acting out their independence through heavy, episodic drinking. But a new University of Cincinnati study, the first of its kind nationally, is showing how binge drinking among adolescents and young adults could be causing serious damage to a brain that's still under development at this age.
