Researchers discover why brain areas fail to work together in autism

In people with autism, the brain areas that perform complex analysis appear less likely to work together during problem solving tasks than in people who do not have the disorder, report researchers working in a network funded by the National Institutes of Health.

People with Parkinson disease can be apathetic without being depressed

People with Parkinson disease can be apathetic without being depressed, and apathy may be a core feature of the disease.

Faulty molecule closely linked to Alzheimer's

A recent study directed by Mount Sinai School of Medicine identifies a faulty molecule in the brain found in cases of mild cognitive impairment (MCI).

Cell phones excite the brain but is that good or bad?

According to a new study the electromagnetic fields from cell phones excite the brain cortex adjacent to it and that possibly has implications for individuals with epilepsy, or other neurological conditions.

Study shows how ADHD drugs Adderall, Ritalin and Dexedrine work in brain

Although millions depend on medications such as Ritalin to quell symptoms of attention deficit hyperactivity disorder (ADHD), scientists have struggled to pinpoint how the drugs work in the brain.

Mild cognitive impairment: Evaluation with 4-T functional MR imaging

Memory loss associated with early Alzheimer's disease (AD) may be linked to altered activity in several areas of the brain, according to a study in the July issue of Radiology.

Altered activity in receptor pair points to further complexity in schizophrenia pathology

Researchers at the University of Pennsylvania School of Medicine, in collaboration with scientists at the City University of New York, have identified a striking dysregulation in neuronal receptor activity in the postmortem brain tissue from patients with schizophrenia.

Resolution of uncertainty in prefrontal cortex

Whether finding your way through an unfamiliar neighborhood to a friend's house or deciding on a political candidate, your brain is adept at adapting.

A core system for the implementation of task sets

Scientists have used data from scans of 183 subjects to identify brain areas that consistently become active in a variety of cognitive tasks, such as reading, learning a rhythm or analyzing a picture.

Hyperscanning - a new approach to studying social interactions

Researchers at Baylor College of Medicine (BCM) have mapped not only where trust forms in the brain but have also uncovered clues as to how humans represent themselves and others as physical responses in their brains.

Activity in the lateral prefrontal cortex reflects multiple steps of future events in action plans

Studies in which monkeys were asked to manipulate computer cursors for fruit juice rewards have revealed that the brain's "executive" center plans behaviors not by specifying movements required for given actions, but rather the events that will result from those actions.

Bipolar disorder causes children to misinterpret facial expressions

Researchers at the National Institute of Mental Health (NIMH) have discovered why children with bipolar disorder tend to be more aggressive and irritable and have poorer social skills than healthy children.

Simple lifestyle changes may improve cognitive function and brain efficiency

A UCLA research study published in the June issue of the American Journal of Geriatric Psychiatry found that people may be able to improve their cognitive function and brain efficiency by making simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction into their daily lives.

Brain research offers insight into mechanisms of prejudice

By scanning subjects' brains while they were thinking about people either politically like or different from them, researchers have found that different areas of the brain are active in the two cases.

Study gives new insight into the stages of recovery of hand muscle control after a stroke

A Queen's study of stroke survivors gives new insight into the stages of recovery of hand muscle control after a stroke, suggesting that patients may benefit from different treatment strategies at different times during the recovery process.

Mental activity leads to mental agility

Scientists have long known that brains need neural activity to mature and that sensory input is most important during a specific window of time called the "critical period" when the brain is primed for aggressive learning.

'Autistic' mice may provide clue to cause of autism

Scientists in the United States have apparently created "autistic" mice by deleting a gene in key parts of the brain.

Pten regulates neuronal arborization and social interaction in mice

While the causes of autism remain complex and mysterious, researchers are steadily adding pieces to its intricate puzzle. In what they believe to be a significant new approach to understanding "autism spectrum disorders" (ASD), researchers have developed a mouse that shows abnormal social interactions and brain hypertrophy characteristic of the disease.

New method found showing how nerve cells can selectively filter and transfer signals

Scientists from Gvttingen and Bochum find evidence for a new mechanism, with which our nerve cells are able to filter signals and transfer them selectively.
