ADHD linked to altered neural activation in bipolar patients

Bipolar disorder patients with and without comorbid attention-deficit hyperactivity disorder differ in neural activation patterns during response inhibition, results from a US study show.

Neurofeedback enhances a brain network responsible for cognitive-control

A breakthrough study conducted in Canada has found that training of the well-known brainwave in humans, the alpha rhythm, enhances a brain network responsible for cognitive-control.

New project aims to devise programs that help reduce risk of cancer

Most people know that smoking, a bad diet, and physical inactivity can lead to catastrophic personal health consequences, including cancer. Yet millions continue to smoke, eat poorly, and fail to get enough exercise.

Exercise may protect the brain from age-related changes

People who exercise later in life may better protect their brain from age-related changes than those who do not, a study suggests.

Two opposing mechanisms support voluntary forgetting of unwanted memories

If only there were a way to forget that humiliating faux pas at last night's dinner party. It turns out there's not one, but two opposite ways in which the brain allows us to voluntarily forget unwanted memories, according to a study published by Cell Press October 17 in the journal Neuron.

New insights into wiring and firing of the social brain

New insights into the wiring and firing of the "social brain" in humans and primates reveals the brain areas important in altruistic motives and behavior, and the brain regions that respond to the pain of discrimination.

Daily sedation interruption does not benefit critically ill, mechanically ventilated patients

For critically ill patients receiving mechanical ventilation, daily sedation interruption did not reduce the duration of mechanical ventilation or appear to offer any benefit to patients, and may have increased both sedation and analgesic use and nurse workload, according to a study appearing in JAMA.

Scientists reveal interaction between the auditory cortex and amygdala

In a study published in the Journal of Neuroscience and funded by the Wellcome Trust, Newcastle University scientists reveal the interaction between the region of the brain that processes sound, the auditory cortex, and the amygdala, which is active in the processing of negative emotions when we hear unpleasant sounds.

Novel neuroimaging technique reveals evidence of cocaine-induced cerebral microischemia

Researchers from the Department of Biomedical Engineering at Stony Brook University have developed a high-resolution, 3D optical Doppler imaging tomography technique that captures the effects of cocaine restricting the blood supply in vessels - including small capillaries - of the brain.

Study to explore effects of intense music training on childhood brain development

The Los Angeles Philharmonic Association, the USC Brain and Creativity Institute and Heart of Los Angeles (HOLA) are delighted to announce a longitudinal research collaboration to investigate the emotional, social and cognitive effects of musical training on childhood brain development.

Alzheimer's disease diagnosis within minutes using a simple brain scan

Groundbreaking research taking place at the University of York could lead to Alzheimer's disease being diagnosed in minutes using a simple brain scan.

Study provides direct evidence for persistent activity in medial entorhinal cortex layer neurons

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that this part of the brain behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.

Prefrontal-limbic network dysfunction in depressive BD

Study findings suggest that patients in the depressive phase of bipolar disorder show dysfunction in prefrontal-limbic networks and associated striatal systems, which can be measured using amplitude of low-frequency fluctuations.

Elsevier announces launch of NeuroImage: Clinical

Elsevier, a world-leading provider of scientific, technical and medical information products and services, announces the launch of NeuroImage: Clinical, a new open access journal, and sister journal to NeuroImage.

Alzheimer's can involve mixture of proteins from different neurodegenerative diseases

Neurodegenerative diseases such as Alzheimer's or Parkinson's are characterised by the loss of nerve cells and the deposition of proteins in the brain tissue. A group of researchers led by Gabor G. Kovacs from the Clinical Institute of Neurology at the MedUni Vienna has now demonstrated that Alzheimer's disease does not just - as previously believed - involve the proteins that are attributed to Alzheimer's, but instead the condition can involve a mixture of interacting proteins from different neurodegenerative diseases.

Navidea commences enrollment in [18F]NAV4694 Phase 2 study for Alzheimer's

Navidea Biopharmaceuticals, Inc., a biopharmaceutical company focused on precision diagnostic radiopharmaceuticals, today announced that enrollment has commenced at two sites participating in its Phase 2, open-label, safety and efficacy PET imaging study of [18F]NAV4694 for detection of cerebral β-amyloid plaque in subjects diagnosed with probable Alzheimer's disease (AD).

‘C’ variant disrupts brain connectivity in children with ASD

Over the past decade, researchers have made great strides in identifying genes that lead to an increased risk of autism spectrum disorders (ASD), which result in a continuum of social deficits, communication difficulties and cognitive delays. But it's still critical to determine how exactly these genetic risk factors impact the brain's structure and function so that better treatments and interventions can be developed.

Moderate exercise may help people cope with future anxiety and stress

Moderate exercise may help people cope with anxiety and stress for an extended period of time post-workout, according to a study by kinesiology researchers in the University of Maryland School of Public Health published in the journal Medicine and Science in Sports and Exercise.

GE Healthcare announces data from [18F]flutemetamol phase III studies on Alzheimer's

GE Healthcare today announced pooled results from phase III brain autopsy and biopsy studies on the investigational PET amyloid imaging agent, [18F]flutemetamol, which showed a strong concordance between [18F]flutemetamol images and Alzheimer's disease-associated beta amyloid brain pathology.

CHOP’s Center for Autism Research receives ACE grant to identify early signs of ASD

The Center for Autism Research at The Children's Hospital of Philadelphia (CHOP) announced today that it will continue its research to identify early signs of autism spectrum disorders (ASD) through a grant from the National Institutes of Health (NIH) Autism Centers of Excellence (ACE) research program.
