“They noted these effects even at low levels of light, suggesting that young children are more sensitive to the effects of light than adults. This was an observational study and did not identify mechanisms that drive the relationship between light exposure and behavior.”

“These exercise-induced changes in the brain were passed on to offspring through microRNAs which help regulate gene expression. This study showed that paternal physical activity is a direct factor driving the offspring’s brain physiology and cognitive behavior.”

“A recent study found that fasting three nonconsecutive days per week promoted more weight loss than daily calorie restriction as part of a comprehensive weight loss program. Researchers assigned 165 adults aged 18 to 60 with a body mass index between 27 and 46 to one of two diet plans.”

“This study shows a clear cause and effect in animals; however, the association between aggressive behavior and sugar consumption in humans remains controversial. Studies have found associations between refined sugar intake and aggression/hyperactivity while others have not.”

“The most recent study showed that serotonin boosts plasticity by influencing a form of learning rate which helps adapt to a new situation. The older study showed that serotonin helps unlearn a previous behavior which helps adapt to a new environment.”

“The researchers also administered several psychological assessments to measure any potentially problematic externalizing (e.g., tendency to break rules and engage in violence) and internalizing features (e.g., depression and anxiety) of behavior.”

“Parents may influence their children through role modeling, easier access to substances at home, and shaping what behaviors seem normal. An authoritative approach may counteract these influences by strengthening adolescents' self-regulation and reducing opportunities for risky behavior.”

“When social drinkers (people without an alcohol use disorder) first consume alcohol, there’s an activity spike in parts of the brain called the ventral striatum and the nucleus accumbens — both of which are key components of the brain’s reward system. Alcohol triggers dopamine release in these areas, contributing to feelings of pleasure and satisfaction and encouraging repeated behavior.”

“Although scientists have identified other lifestyle behaviors that can help prevent the build-up of amyloid plaques by boosting the capacity for glymphatic clearance – such as exercise and adequate intake of omega-3 – the most important factor by far is a good night's sleep, especially deep sleep.”

“In a first of its kind study on nicotine addiction, scientists measured a behavior that can be similarly quantified across species like humans and rats, the responses to rewards during nicotine withdrawal.”
