Autism: Changes in RNA editing in the brain play an important role, scientists find

A team of scientists has discovered important clues as to what happens in the brains of people with autism. The new insights involve RNA editing, in which modifications in RNA alter nucleotides, whose patterns carry the data required for constructing p…

Females find social interactions to be more rewarding than males, study reveals

Females find same-sex social interactions to be more rewarding than males, and females are more sensitive to the rewarding actions of oxytocin than males, according to a new research on the brain mechanisms that determine the rewarding properties of so…

Difference in brain connectivity may explain autism spectrum disorder

Researchers have identified a possible mechanism of human cognition that underlies autism spectrum disorders, or ASD. They found there was brain overconnectivity in the unimodal-subcortical connections and brain underconnectivity in the supramodal-subc…

With autism on the rise, science is on the hunt for answers

Scientists have used two brain imaging techniques to study autism. They found a correlation between brain activity, amino acid byproduct concentrations, and severity of autism diagnosis.

Puerto Rico’s ‘fear lab’ mentors neuroscience rigor amid diversity

A lineage of young neuroscientists from diverse backgrounds trace their scientific roots to a ‘fear lab’ in Puerto Rico that the National Institutes of Health has been supporting for two decades. A crucible for studies of fear extinction, the lab has s…

We need to fine-tune our ‘maps’ of the visual cortex

Monkey brain scans have revealed new information about the part of the brain that processes visual information.

Mental health disorders common following mild head injury

A new study reveals that approximately 1 in 5 individuals may experience mental health symptoms up to six months after mild traumatic brain injury (mTBI), suggesting the importance of follow-up care for these patients. Scientists also identified factor…

Researchers ID, treat faulty brain circuitry underlying symptoms of schizophrenia

In a first-of-its-kind study, researchers have determined the underlying anatomical cause of certain symptoms of schizophrenia, then ameliorated them with non-invasive brain stimulation. The scientists reported that these symptoms arise from a breakdow…

Draining blood from bleeding stroke may prevent death

A minimally invasive surgery combining the use of a clot-busting drug and a catheter to drain blood from the brain of hemorrhagic stroke patients reduced swelling and improved patients’ prognoses, according to preliminary research.

Are tattoos linked to poor health and risky behavior?

As tattoos become increasingly popular, a new study examines the relationship between body art, physical and mental health, and risky behavior.
