Researchers continue to explore how ketamine brings about fast-acting relief for people with depression. In a new experiment, scientists tested how brain activity changes under different conditions, shedding light on the complex pathways involved in the treatment response.

A strand of hair might seem like an unlikely window into a child’s psychological wellbeing, but new research from the University of Waterloo suggests that measuring stress hormones in hair samples could help identify which children with chronic illnesses are most at risk for developing serious mental health problems.

The four-year study of 244 Canadian children reveals a concerning pattern: more than two-thirds of kids living with chronic physical conditions showed persistently elevated levels of cortisol, the body’s primary stress hormone, measured through their hair. These children also displayed more symptoms of depression, anxiety, and behavioral problems compared to peers whose stress levels naturally declined over time.

Supported by the Allen Institute’s OpenScope program, the findings could help us better understand neuropsychiatric disorders like schizophrenia and reshape our understanding of vision

Scientists have uncovered a mechanism by which nanoplastics impair brain energy metabolism, offering new clues into environmental contributions to neurodegeneration.

Researchers discovered how the brain flexibly switches communication pathways depending on context, balancing between memory recall and processing new information.
