Study examines how our brain generates consciousness and loses it during anesthesia

Medically-induced loss of consciousness during anesthesia is associated with a break-down of brain connectivity at the anatomical macro scale - across cortical areas - yet what role brain micro circuitry plays in LOC remains unclear.

Researchers find potential link between autism and antidepressant use during pregnancy

An international team led by Duke-NUS Medical School has found a potential link between autistic-like behavior in adult mice and exposure to a common antidepressant in the womb.

Study provides potential new targets for treating epilepsy

A new study provides potential new targets for treating epilepsy and new fundamental insights into the relationship between neurons and their glial "helper" cells.

Autism diagnoses in children as young as 14 months appears to be remarkably stable

Diagnoses of autism spectrum disorder by trained professionals in children as young as 14 months are remarkably stable, suggesting that accurate screening and earlier treatment is feasible, report scientists at University of California San Diego School of Medicine in a study publishing online April 29, 2019 in JAMA Pediatrics.

Veterans, active-duty service members with PTSD and mTBI have larger amygdalas, finds study

A new study finds that veterans and active-duty service members with combat-related PTSD and mild traumatic brain injury had larger amygdalas--the region of the brain that processes such emotions as fear, anxiety, and aggression--than those with only brain injuries.

Pencil beam scanning proved best for preserving cognitive functions in children with brain tumor

A comparison of three types of radiotherapy for children's brain tumors suggests that a type of proton therapy called pencil beam scanning offers the best hope of preserving cognitive functions.

Neuroscientists investigate how olfactory brain influences memory formation

How sensory perception in the brain affects learning and memory processes is far from fully understood. Two neuroscientists of Ruhr-Universität Bochum have discovered a new aspect of how the processing of odors impacts memory centers.

Researchers use nitrous oxide to unravel rapid function of antidepressant mechanisms

Ketamine is commonly used in emergency medicine as an anesthetic drug. Later it was discovered to have rapid-acting antidepressant effects, but the mechanisms by which ketamine alleviates depression are still unknown.

Cannabis, Alcohol and the Epigenome

With the legalization of cannabis in many US states, we explore the epigenetic effects of cannabis, cannabis-derived products, and alcohol.

Study looks at the impact on criminal persistence of head injuries

Researchers have sought to identify the factors that promote or contribute to criminal persistence--that is, the likelihood that offenders will continue to offend.

Study: Involvement of prefrontal cortex areas decreases with aging

Researchers from HSE University and York University have become the first to analyze the results of 82 functional neuroimaging studies on working memory mechanisms in different adult age groups.

Scientists discover trigger region for absence epileptic seizures

Scientists have discovered a neurological origin for absence seizures--a type of seizure characterized by very short periods of lost consciousness in which people appear to stare blankly at nothing.

Myelination deficits cause abnormal hypersocial behavior associated with Williams syndrome

A new Tel Aviv University study finds that gene deletion or deficiency in neurons is responsible for the abnormal hypersocial behavior associated with Williams syndrome, a rare disorder affecting 1 in 10,000 people around the world.

Combination-imaging technique provides new window into macaque brain connections

Researchers can now see how the two sides of the living brain mirror each other thanks to a new combination-imaging technique.

Study investigates how early blindness shapes sound processing

Adults who lost their vision at an early age have more refined auditory cortex responses to simple sounds than sighted individuals, according to new neuroimaging research published in JNeurosci.

Brain areas linked to memory and emotion aid odor navigation in humans

Species like dogs and rodents use their sense of smell to navigate toward desirable items and places and away from those they should avoid.

MIT scientists reverse some behavioral symptoms of rare neurodevelopmental disorder

Williams Syndrome, a rare neurodevelopmental disorder that affects about one in 10,000 babies born in the United States, produces a range of symptoms including cognitive impairments, cardiovascular problems, and extreme friendliness, or hypersociability.

Two studies uncover brain mechanisms underlying decision making process

New research conducted in the Cognitive Neuroscience group of SISSA shows that a perceptual decision - recognizing an object and taking the appropriate action - is triggered as soon as the brain's processing networks accumulate the exact right quantity of sensory information.

Disruptive behaviors in autistic children linked to reduced brain connectivity

More than a quarter of children with autism spectrum disorder are also diagnosed with disruptive behavior disorders.

Researchers map auditory sensory system of the mouse brain

University of Oregon neuroscientists report that two areas of the mouse brain combine representations of what is heard and anticipated, guiding behavior that leads mice to the best reward.
