A large Finnish registry study reveals that many children, especially boys who begin ADHD medication between ages 6 and 8, remain on treatment for more than seven years. While the average duration of ADHD medication was over three years, a quarter of treated children remained on it for over seven, and some for nearly a decade.
A new study reveals that a small cluster of cells near the brain's "blue spot"—the locus coeruleus—helps regulate arousal, attention, and stress responses. These peri-LC neurons modulate the locus coeruleus by releasing GABA, which reduces its activity and dampens the release of norepinephrine.
Sleeping more than nine hours a night may be detrimental to brain health, particularly for individuals experiencing symptoms of depression, according to a new study. Researchers analyzed data from nearly 2,000 dementia-free adults and found that long sleep duration was associated with worse performance in memory, visuospatial ability, and executive function.
Large language model (LLM) AI agents, when interacting in groups, can form shared social conventions without centralized coordination. Researchers adapted a classic “naming game” framework to test whether populations of AI agents could develop consensus through repeated, limited interactions.
A new study tracking nearly half a million participants over 12 years has revealed a strong, independent link between loneliness and an increased risk of hearing loss. Even after adjusting for genetic risk, health conditions, and lifestyle factors, lonely individuals had a 24% higher chance of developing hearing loss, especially sensorineural types.
A new study reveals how rats can learn to fear through inference, offering insights into the neural basis of higher-order emotions. By pairing a neutral sound and image, then associating the image with an unpleasant experience, researchers showed that rats later feared the sound alone—demonstrating inferred emotional learning.
A new study reveals that many self-identified incels reject employment not only due to mental health challenges, but as a deliberate expression of identity reinforced by online communities. By analyzing over 1,200 forum posts, researchers found that incel spaces often celebrate unemployment and isolation as signs of ideological purity, pressuring others to remain disengaged from work or education.
Preliminary research suggests that working more than 52 hours per week may physically alter brain regions involved in emotional regulation, memory, and decision-making. MRI scans from healthcare workers revealed increased grey matter volume in key areas like the middle and superior frontal gyri and the insula.
A new study finds that vegetarians reject meat with the emotion of disgust, rather than simple distaste, mirroring the strong aversion meat-eaters feel toward taboo foods like human flesh or feces. In contrast, disliked vegetables like beets or sprouts are typically rejected due to distaste—an aversion based on taste or texture.
A new review reveals key differences in how stress hormone systems function in primate versus rodent brains, offering insight into why treatments for stress-related disorders often fail in humans. Researchers found that corticotropin releasing factor (CRF) interacts with dopamine circuits in more complex and widespread ways in primates, with dopamine neurons often releasing multiple neurotransmitters.
