AI Models Form Theory-of-Mind Beliefs

Researchers showed that large language models use a small, specialized subset of parameters to perform Theory-of-Mind reasoning, despite activating their full network for every task. This sparse internal circuitry depends heavily on positional encoding, especially rotary positional encoding, which shapes how the model tracks beliefs and perspectives.

Stress Undermines Brain Circulation, Increases Dementia Risk

Researchers found that a rare class of neurons—type-one nNOS neurons—plays a central role in regulating brain blood flow and coordinating neural activity in mice. Removing these stress-vulnerable cells caused major drops in vessel oscillations and widespread reductions in electrical signaling, suggesting a crucial link between neuron loss, blood-flow decline, and brain-function impairment.

Low Choline Could Be a Hidden Driver of Anxiety

A large meta-analysis of 25 studies found that people with anxiety disorders have significantly lower levels of choline, a vital brain nutrient, compared to individuals without anxiety. This reduction was especially pronounced in the prefrontal cortex, which helps regulate emotion and behavior.

New Therapy Reshapes Images That Fuel Psychosis

A new imagery-focused therapy called iMAPS may help people with psychosis gain control over disturbing mental images that fuel paranoia, fear, and hallucinations. In a feasibility trial of 45 participants, the approach showed strong patient engagement and meaningful reductions in distress by teaching individuals to understand, transform, and re-script intrusive images.

New Drug Exposes Hidden Subtypes of Psychosis

A new study examining real-world hospital data reveals early indicators of who is most likely to benefit from Cobenfy, the first new schizophrenia drug mechanism approved in 50 years. Patients with strong negative symptoms responded best to the xanomeline–trospium combination, showing notable improvements in social behavior and mood.

Meditation Retreat Sparks Rapid Brain & Immune System Changes

A week-long retreat combining meditation and mind-body healing produced significant changes in brain activity and blood biology, demonstrating how consciousness-based practices can transform physical health. Participants showed reduced default-mode activity, enhanced neural connectivity, elevated natural opioids, immune activation, and metabolic shifts—effects that extended beyond the brain into the entire body.

Oxidative Stress May Drive Repetitive Behaviors Linked to Autism, OCD

A new study shows that oxidative stress—an imbalance between damaging molecules and antioxidants—may contribute to repetitive behaviors observed in mice, similar to those seen in autism spectrum disorder and schizophrenia. Researchers found that higher levels of oxidative stress biomarkers, including glutathione and specific proteins, were linked to more severe stereotypies in young mice.

Early Trauma Hardwires the Brain for Aggression and Self-Harm

A new study reveals that aggression and self-harm share a biological foundation in the brain’s response to early-life trauma. Researchers discovered that trauma increases activity in calcium channels within a neural circuit connecting the nucleus reuniens and hippocampus, amplifying pain processing and impulsive behavior.

Antibiotic Doxycycline May Cut Schizophrenia Risk

A large population-based study suggests that doxycycline, a common antibiotic, may reduce the risk of schizophrenia when prescribed to adolescents receiving mental health care. Researchers analyzed data from more than 56,000 young patients and found that those who took doxycycline had a 30–35% lower chance of developing schizophrenia later in life.

AI Can Spot Lies, But Not as Well as Humans Can

A large-scale study tested whether AI personas can detect when humans are lying—and found that while AI can sometimes spot deception, it’s still far from trustworthy. Across 12 experiments involving 19,000 AI participants, the systems performed inconsistently, showing a strong bias toward identifying lies rather than truths.

AI Maps the Brain’s Hidden Bridge, Revealing Genetic Links to Mental Health

For the first time, scientists have mapped the genetic architecture of the brain’s communication bridge—the corpus callosum—using AI and MRI data from over 50,000 people. The study uncovered dozens of genes that shape this vital structure’s size and thickness, many active during prenatal development when the brain’s wiring is established.

Brain Circuit Found to Shape Risk and Impulse Differently by Sex

Researchers exploring risky decision-making in rats found that a specific reward-related neural circuit influences impulsivity and risk-taking in complex ways that depend on timing and biological sex. Manipulating the circuit during the learning phase of a gambling task altered risky choices differently in males and females, while manipulation after learning affected motor impulsivity in both.
