Cannabis Linked to Reduced Insomnia and Anxiety
Summary: A new study suggests cannabis-based medical products may help people with insomnia sleep better over the long term. Across 124 patients followed for up to 18 months, participants consistently…
Big Five No More? New Study Uncovers Hidden Personality Traits
Summary: For 40 years, the Big Five personality model has dominated psychology, but new research suggests it may be incomplete. Using taxonomic graph analysis, researchers mapped personality from the ground…
High-THC Cannabis Linked to Psychosis and Addiction
Summary: A systematic review of nearly 100 studies found that high-THC cannabis products are linked to negative mental health outcomes, particularly psychosis, schizophrenia, and cannabis use disorder. While some therapeutic…
Brain Study Reveals Circuit Controlling Depression and Anxiety
Summary: A new study identifies brain area 46 in the marmoset dorsolateral prefrontal cortex as a key regulator of mood-related behavior. When this region was inactivated, the animals showed less…
How Stress Types Differently Impact Brain and Behavior
Summary: Stress is a universal experience, but not all stress affects the brain in the same way. A new study in rats reveals that acute stress provokes anxiety-like behaviors, especially…
Eight New Genes Linked to Schizophrenia Revealed
Summary: The largest exome-sequencing study of schizophrenia to date has uncovered eight new genes tied to the disorder. Two genes, STAG1 and ZNF136, were strongly implicated, while six others showed…
Highly Sensitive People Face Greater Mental Health Risks
Summary: A large-scale meta-analysis of 33 studies has shown that highly sensitive individuals are more prone to common mental health problems, including depression, anxiety, PTSD, and avoidant personality disorder. Sensitivity…
Bipolar Mood Shifts Linked to Insulin Signaling in the Pancreas
Summary: A new study uncovers a pancreas–hippocampus feedback loop that may help explain mood swings in bipolar disorder. Using patient-derived pancreatic islets, researchers found reduced insulin secretion linked to elevated…
Brain Circuit Model Reveals How Striatum Shapes Everyday Decisions
Summary: Researchers have developed a computational framework that maps how the striosomal compartment of the striatum governs everyday decision-making. By integrating biology, decision theory, and mathematical modeling, the study reveals…
