Posttraumatic brain activity predicts resilience to PTSD

After a traumatic experience, most people recover without incident, but some people — between 2% and 10% — develop posttraumatic stress disorder (PTSD), a mental health condition that can cause debilitating symptoms of anxiety due to emotional dysreg…

Molecular mechanism of psychological loss

Psychological loss can occur when someone loses a job, loses a sense of control or safety or when a spouse dies. Such loss, which erodes well-being and negatively impacts quality of life, may be a common experience but little is known about the molecul…

Scientists find new evidence to explain how we pay attention

A team of researchers has uncovered new clues about how chemicals released by brain cells regulate our attention span.

Suppressing negative thoughts may be good for mental health after all, study suggests

The commonly-held belief that attempting to suppress negative thoughts is bad for our mental health could be wrong, a new study suggests. Researchers trained 120 volunteers worldwide to suppress thoughts about negative events that worried them, and fou…

Decoding depression: Researchers identify crucial biomarker that tracks recovery from treatment-resistant depression

A team of leading clinicians, engineers, and neuroscientists has made a groundbreaking discovery in the field of treatment-resistant depression. By analyzing the brain activity of patients undergoing deep brain stimulation (DBS), a promising therapy in…

Why are the brain’s nerve cells organized into modules?

Scientists have revealed that the outer part of our brain (the cortex) is skilled at managing all the info it gets from the outside world thanks to special groups of nerve connections called modules, which work together but also independently.

Exposure to plasticizers in pregnancy associated with smaller volumetric measures in the brain and lower IQ in children

A study with 775 mother-child pairs in Rotterdam (The Netherlands) finds an association with maternal exposure to certain plasticizers (phthalates) and smaller volumetric measures in the brain of children as well as lower IQ at age 14

Researchers ‘bioprint’ living brain cell networks in the lab

Researchers have successfully used ‘bioinks’ containing living nerve cells (neurons) to print 3D nerve networks that can grow in the laboratory and transmit and respond to nerve signals.

New blood marker can identify Parkinsonian diseases

Is it possible that a single biomarker can detect all types of diseases related to dopamine deficiency in the brain? Yes, that’s what a research group is discovering. ‘We have observed that an enzyme in cerebrospinal fluid and in blood is a useful mark…

Living in a disadvantaged neighborhood affects food choices, weight gain and the microstructure of the brain

A new study finds poor quality of available foods, increased intake of calories from foods high in trans-fatty acids, and environments that do not foster physical activity, all prevalent in disadvantaged neighborhoods, disrupt the flexibility of inform…
