Animal studies have described “low road” pathways that rush sensory information from the thalamus to the amygdala. A brain imaging study of 113 people now maps several such routes in humans, with some far more consistent than others. dlvr.​it/TW0FBT

Young people who met criteria for a psychotic disorder at 18 had slightly smaller heads from birth through age 15. But once height was taken into account, the difference largely disappeared, pointing to overall growth rather than brain-specific changes. dlvr.​it/TW10WM

Feeling buried in debt hurts living standards more than the actual math: A study of Polish borrowers finds that feeling over-indebted is more strongly linked to struggles affording everyday needs than actual debt-to-income ratios, as stressed families cut… dlvr.​it/TW10TZ

Petting a dog after a stressful task didn’t speed recovery, but in a new experiment it was followed by calmer brain and heart responses when dog owners faced a second stress test soon after. dlvr.​it/TW09kk

A massive analysis of Swedish administrative records reveals that higher cognitive abilities strongly predict prosocial behaviors. Individuals with higher general intelligence are consistently more likely to donate to charity, vote in elections, and buy… dlvr.​it/TW0wtT

There may be a physical reason lying down feels good when you��re hurting. Pain sensitivity was modestly lower while lying flat, possibly because more blood returns to the chest and activates the body’s pressure sensors. dlvr.​it/TW0s8F

Children with ADHD process unexpected sounds differently than their peers, but these brain responses change as they grow. New research shows heightened sensitivity to sudden noises in early childhood gives way to blunted responses in middle childhood. dlvr.​it/TW05DM

During psychiatric treatment, a patient's personality and depression symptoms change in tandem. A new study reveals that high neuroticism slows recovery across multiple symptoms, while extraversion and agreeableness may help patients bounce back faster. dlvr.​it/TW0mZD

Cannabis is often a group activity in college, but the pattern looks different among heavier users. Students who used more often shared less in a hypothetical sharing task and were less likely to use mostly with others. dlvr.​it/TW00RH

Older adults described both one-time events and recurring routines with more general facts and fewer specific details than younger adults did, yet both age groups struggled similarly when they had to switch between memory types. dlvr.​it/TW0k6m

Telling someone online that they eat meat because they don’t care about the planet tends to backfire into defensiveness rather than persuasion. The same moral criticism from a stranger provoked even more pushback when it arrived as a private direct message… dlvr.​it/TVzxsj

A large longitudinal study reveals that early childhood intelligence scores can predict the pace at which gray and white matter develop during adolescence, highlighting distinct patterns of brain refinement and network specialization. dlvr.​it/TW0gpF

Childhood trauma leaves a physical mark on the brain's structure, but heavy drinking might hide the evidence. A new brain imaging study reveals how alcohol use disorder can overwrite the subtle neurodevelopmental scars left by early life abuse and neglect. dlvr.​it/TVzvgd

A third of U.​S. teen boys in a new survey said they follow Andrew Tate at least a little. Those who did tended to favor emotional detachment, dominance, toughness, and rejecting femininity, even after accounting for their parents' messages. dlvr.​it/TW0dcj

Childless couples who cared for a lifelike baby doll showed no testosterone change at first, but after a weekend with the doll at home, men’s and women’s levels fell by about 9 to 12 percent during joint caregiving. dlvr.​it/TVzsP0

Among young adults with more childhood trauma, weaker communication between the hippocampus and the brain’s reward hubs was linked to a reduced ability to look forward to pleasurable experiences, but not to enjoying them in the moment. dlvr.​it/TW0bX0

A meta-analysis of 11 long-running studies covering up to 134,515 workers found that rising pay tended to precede small gains in conscientiousness and emotional stability, along with slight drops in agreeableness and extraversion. dlvr.​it/TVzqNM
