A new finding from researchers at Georgetown University Medical Center shows that the learning process of associating cues with rewards can be altered by increased or decreased activity of a specific protein in the brain. Knowing when to respond positively to cues that result in beneficial outcomes or rewards vs. ignoring cues that result in bad habits, such as smoking addiction, is an essential part of learned behaviors.

Reopening schools during the COVID-19 pandemic was linked with significantly lower rates of mental health diagnoses among children, including anxiety, depression, and attention-deficit/hyperactivity disorder (ADHD), and a drop in related health care spending, according to a new study from researchers at Harvard T.H. Chan School of Public Health and colleagues. The benefits were especially pronounced among girls.

A new machine-learning method from CMU's He lab analyzes all major epileptic brain signals in one framework. The technique presents both a technical breakthrough and promising new direction for noninvasive presurgical planning.

A study funded in part by the National Institutes of Health (NIH) has revealed important insights into the genetics of deposits in the eye, known as reticular pseudodrusen (RPD), that are linked to greater risk of vision loss among people with age-related macular degeneration (AMD). The study underscores that AMD is not one disease and highlights the need for novel treatment approaches.
