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.

Relatives of schizophrenia patients show cortical thinning

Patients with schizophrenia and their unaffected relatives show significant cortical thinning compared with mentally healthy individuals without such a family history, researchers report.

LED light instantly triggers or reverses depression-like behavior in rodents

A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress, a study supported by the National Institutes of Health has found. When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced pleasure-seeking - they avoided other animals and lost their sweet tooth.

Cognitive retrieval impaired in schizophrenia

Patients with schizophrenia show impairments in the autobiographical memory retrieval brain network, French researchers report.

Carbon nanotubes can help regulate chloride levels in nerve cells that contribute to neural injuries

A nanomaterial engineered by researchers at Duke can help regulate chloride levels in nerve cells that contribute to chronic pain, epilepsy, and traumatic brain injury.

Brain scans could help scientists uncover mechanisms underlying mental fatigue

We all perhaps know the feeling of mental exhaustion, but what does it mean physiologically to have mental fatigue? A new study carried out using brain scans could help scientists uncover the neurobiological mechanisms underlying mental fatigue.

Wellcome Trust researchers discover how brain assesses confidence in its decisions

Wellcome Trust researchers have discovered how the brain assesses confidence in its decisions. The findings explain why some people have better insight into their choices than others.

ADHD comorbidity confounds brain findings in bipolar disorder

Structural brain abnormalities found in patients with bipolar disorder may have been wrongly attributed to the condition and in fact be associated with comorbid attention–deficit hyperactivity disorder, US researchers believe.

Western University research could lead to better treatments for PTSD and drug addiction

New research from Western University could lead to better treatments for Post-Traumatic Stress Disorder (PTSD) and drug addiction by effectively blocking memories. The research performed by Nicole Lauzon, a PhD candidate in the laboratory of Steven Laviolette at Western's Schulich School of Medicine & Dentistry has revealed a common mechanism in a region of the brain called the pre-limbic cortex, can control the recall of memories linked to both aversive, traumatic experiences associated with PTSD and rewarding memories linked to drug addiction.

Nerve stimulation improves hand use in spinal cord injury patients

A method combining transcranial magnetic stimulation with electrical stimulation of peripheral nerves in the wrist temporarily improves hand use in spinal cord injury patients, show research findings published in Current Biology.

Obstructive sleep apnea affects women more severely than men

Women suffering from sleep apnea have, on the whole, a higher degree of brain damage than men with the disorder, according to a first-of-its-kind study conducted by researchers at the UCLA School of Nursing.

Chronic focal brain cooling suppresses seizures during wakefulness

Neuroscientists from Japan's Yamaguchi University today reported during the 66th annual scientific meeting of the American Epilepsy Society (AES) that chronic focal brain cooling suppresses seizures during wakefulness and achieves the effect without significantly affecting brain function. Their research, and that of others in the field, provides critical evidence that this approach to seizure control has reached a stage where testing in humans will soon be possible.

Brain study provides new insights into how recognition is connected with emotion and morality

People are able to detect, within a split second, if a hurtful action they are witnessing is intentional or accidental, new research on the brain at the University of Chicago shows.

Reduced production of myelin may play role in development of mental illness: Study

Reduced production of myelin, a type of protective nerve fiber that is lost in diseases like multiple sclerosis, may also play a role in the development of mental illness, according to researchers at the Graduate School of Biomedical Sciences at Mount Sinai School of Medicine.
