Brain circuit problem likely sets stage for the 'voices' that are symptom of schizophrenia

Researchers at St. Jude Children's Research Hospital identified a disrupted brain circuit that may contribute to auditory hallucinations in schizophrenia. The study, published in Science, suggests that reducing information flow between two brain structures involved in processing auditory information sets the stage for stress triggers.

Study uncovers why autism is more common in males

A large cohort study found that females diagnosed with autism spectrum disorder (ASD) and other neurodevelopmental disorders have a greater number of harmful genetic mutations than males. This suggests that the female brain requires more extreme genetic alterations to produce symptoms of ASD or neurodevelopmental disorders.

Rebuilding the brain after stroke

Researchers have discovered a potential therapy to enhance brain repair after a stroke by stimulating the brain's inherent plasticity with molecular components of stem cells. This approach has shown promising results in promoting neurological recovery and may lead to revolutionary treatments for other diseases.

Peripheral immune system may regulate vulnerability to depression

A study suggests that immune cells outside the brain may contribute to depression, with elevated levels of interleukin-6 linked to increased depressive behaviors in rodents. Researchers found that mice transplanted with high-responding donors exhibited increased depression-like behaviors compared to those with low-responding donors.

Creating a 'window' to the brain

UC Riverside researchers have created a novel transparent skull implant made of yttria-stabilized zirconia, allowing doctors to aim laser-based treatments without repeated craniectomies. This technology has strong potential for positive impact on patients with life-threatening neurological disorders.

Distinct brain disorders biologically linked

A rare genetic deletion of the TOP3B gene has been identified as a common biological pathway for both schizophrenia and a learning disorder associated with autism, increasing susceptibility by two-fold. The study uncovers an important biological process underlying these brain disorders, potentially leading to new drug targets.

The protein profile of restless leg syndrome

A study published in Fluids and Barriers of the CNS found a significantly altered level of six specific proteins in people with restless leg syndrome (RLS), consistent with iron deficiency, dopamine dysregulation, and inflammation. The discovery could lead to new treatments for RLS and its associated cardiovascular disease risk.

Ultrasound reveals autism risk at birth

A new study found that low-birth-weight newborns with enlarged ventricles on an ultrasound are seven times more likely to be diagnosed with autism later in life. The research suggests that an early brain abnormality may indicate a higher risk of developing autism.

Vision restored with total darkness

A study by Dalhousie University researchers found that immersion in total darkness can rapidly restore vision in kittens with amblyopia. The recovery depends on the loss of neurofilaments holding the visual system in place. Darkness therapy holds promise for treating children with amblyopia, but more research is needed to determine the...

Human brain is divided on fear and panic

Researchers have identified multiple brain regions responsible for generating fear and panic, including the amygdala, brainstem, diencephalon, and insular cortex. The findings suggest that an intact amygdala normally inhibits panic, and its absence can lead to anxiety-related conditions.

A gut feeling about neural stem cells

Scientists at the University of Melbourne have successfully transplanted neural stem cells into mice, which then migrated to the gut and developed into functional neurons. This breakthrough could lead to new treatments for intestinal motility disorders such as Hirschsprung's disease.
