Study: General anesthesia in early infancy unlikely to have lasting effects on developing brains

A single hour of general anesthesia in early infancy—longer than is necessary to perform the most common types of minor surgeries in childhood—does not result in measurable neurodevelopmental or behavioral problems up to the age of 5 years, according to the first randomized trial of its kind involving 722 infants in seven countries, published in The Lancet.

Lifetime adversity, increased neural processing during trauma combine to intensify core PTSD symptoms

Lifetime adversity and increased neural processing during a traumatic event combine to increase the frequency of intrusive traumatic memories and the distress they cause, according to a new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

Social threat learning has a strong effect on our decision-making

Learning what is dangerous by watching a video or being told (known as social learning) has just as strong an effect on our decision-making as first-hand experience of danger, researchers at Karolinska Institutet in Sweden report.

Researchers identify brain pathways of aversion

What happens in the brain when we feel discomfort? Researchers at Karolinska Institutet in Sweden are now one step closer to finding the answer. In a new study published in the journal Molecular Psychiatry they identify which pathways in the mouse brain control behavior associated with aversion.

Movement of wrist bones revealed by MRI and computer modeling

We use our wrists constantly, but how do they work? In a just-published Journal of Biomechanics article, the researchers proved a longtime assumption about individuals' right and left wrists, while also finding differences between wrists of males and females: discoveries that could help inform and guide future treatments.

Study shows how neuroactive steroids inhibit activity of pro-inflammatory proteins

For the first time, scientists discovered how neuroactive steroids naturally found in the brain and bloodstream inhibit the activity of a specific kind of protein called Toll-like receptors, which have been known to play a role in inflammation in many organs, including the brain.

Photoacoustic imaging accurately measures the temperature of deep tissues

Measuring a fever is usually pretty simple: place a thermometer under a patient's tongue and get an accurate temperature reading within 30 seconds. But that simplicity does not translate when it comes to measuring the temperatures of specific tissues deep inside the body.
