Genomic study reveals role for hypothalamus in inflammatory bowel disease

Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies (GWAS), researchers have found significant genetic correlations between inflammatory bowel disease (IBD) and stress and depression.

Mouse studies link some autism to brain cells that guide sociability and platonic love

Researchers report that new experiments with genetically engineered mice have found clear connections among a range of autism types and abnormalities in brain cells whose chemical output forges platonic feelings of love and sociability.

Should I run, or should I not? The neural basis of aggression and flight

Researchers have investigated the mechanism behind defensive behavior in mice. They have identified a specific area of the brain that encodes both spatial and threat cues to drive location-specific defensive responses.

Brainstem neurons control both behavior and misbehavior

A recent study reveals how gene control mechanisms define the identity of developing neurons in the brainstem. The researchers also showed that a failure in differentiation of the brainstem neurons leads to behavioral abnormalities, including hyperacti…

Graphene-based memory resistors show promise for brain-based computing

As progress in traditional computing slows, new forms of computing are coming to the forefront. A team of engineers is attempting to pioneer a type of computing that mimics the efficiency of the brain’s neural networks while exploiting the brain’s anal…

Study helps explain why motivation to learn declines with age

Neuroscientists have identified a brain circuit critical for learning to make decisions that require evaluating the cost or reward of an action. They showed this circuit is negatively affected by aging and in Huntington’s disease.

Age and pre-existing conditions increase risk of stroke among COVID-19 patients

Fourteen out of every 1,000 COVID-19 patients admitted to hospital experience a stroke, a rate that is even higher in older patients and those with severe infection and pre-existing vascular conditions, according to a new report.

Small brain device proves big game changer for severely paralysed patients

A tiny device the size of a small paperclip has been shown to help patients with upper limb paralysis to text, email and even shop online in the first human trial.

What EEGs tell us about COVID-19 and the brain

A systematic review of hundreds of cases of patients diagnosed with COVID-19 helps painting a broader picture of how COVID-19 affects the brain.

‘White matter lesion’ mapping tool identifies early signs of dementia

A new tool for analyzing tissue damage seen on MRI brain scans can detect with more than 70% accuracy early signs of cognitive decline, new research shows.
