Brain circuit responsible for cocaine withdrawal-induced anxiety and relapse-related behavior

New research finds that drug withdrawal-induced anxiety and reinstatement of drug seeking behaviors are controlled by a single pathway in the brain and centered around dopamine cells.

Brain networks can play role in weight-loss success

When it comes to weight loss, the old adage it’s all in your head may be true. Scientists have shown that two specific networks in the brain can strongly influence how successful a person will be when trying to lose weight.

Finding your car in a parking lot relies on this newly discovered brain circuit

When exploring a new environment, mice make use of a unique long-distance connection in the brain that prompts them to pay attention to the most salient features of the environment, according to new research. The link, originating in the prefrontal cor…

Cognitive impairment from severe COVID-19 equivalent to 20 years of aging, study finds

Cognitive impairment as a result of severe COVID-19 is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, say scientists.

‘Resetting’ the injured brain offers clues for concussion treatment

New research in mice raises the prospects for development of post-concussion therapies that could ward off cognitive decline and depression, two common conditions among people who have experienced a moderate traumatic brain injury.

Gene therapy reverses effects of autism-linked mutation in brain organoids

Scientists use lab-grown human brain tissue to identify neural abnormalities in Pitt-Hopkins Syndrome and show gene therapy tools can rescue neural structure and function.

AI-enabled ECGs may identify patients at greater risk of stroke, cognitive decline

Atrial fibrillation, the most common cardiac rhythm abnormality, has been linked to one-third of ischemic strokes, the most common type of stroke. But atrial fibrillation is underdiagnosed, partly because many patients are asymptomatic.

New research could help identify babies at risk of brain bleeds

Researchers have uncovered a new way to help identify babies and fetuses at high-risk of developing brain bleeds, paving the way for better early intervention.

New insights on the importance of skull channels for brain health

Researchers who previously discovered channels in the skull have found that cerebrospinal fluid can exit the brain through these channels to reach the skull’s bone marrow, which can detect and respond to infection or injury. Tapping into this process m…

Stress, anxiety and depression during pregnancy may hinder toddler’s cognitive development

Women’s elevated anxiety, depression and stress during pregnancy altered key features of the fetal brain, which subsequently decreased their offspring’s cognitive development at 18 months. These changes also increased internalizing and dysregulation be…
