Summary: As generative artificial intelligence rapidly synthesizes paintings, music, and literature, a new theoretical framework published in AI & Society reframes what human creative cognition truly means. The paper presents the “decoupling thesis,” arguing that while AI can bypass years of technical training to produce accomplished works, it separates the act of creating from the … Read more
Summary: A study led by the Chinese Academy of Medical Sciences shows that peripheral immune cells that enter the hippocampus during acute sepsis can become long-lived residents, driving chronic neuroinflammation and lasting cognitive deficits. These monocyte-derived macrophages persistently produce pleiotrophin (PTN), activating resident microglia through alpha-beta2 (CD11b) signaling and provoking abnormal myelin engulfment. Preventing the … Read more
Summary: A small, randomized pilot study led by psychiatrists and biomedical engineers at NYU Langone Health found that a single non-invasive session of MRI-guided transcranial ultrasound stimulation (TUS) targeting the globus pallidus interna (GPi) safely reduced delusional symptoms in people living with schizophrenia and schizoaffective disorder. Ten minutes of focused ultrasound produced a statistically significant … Read more
Summary: USC researchers analyzing living hippocampal tissue removed during epilepsy surgery found that a higher density of abnormal, immature astroglia in the hippocampus is associated with poorer fluid intelligence — the capacity to reason, solve novel problems, and adapt to unfamiliar situations. This direct cellular evidence from living human tissue highlights a non-neuronal driver of … Read more
Summary: A large prospective study of 2,435 pregnant women in Japan found that developing restless legs syndrome (RLS) during pregnancy is associated with about a threefold higher risk of perinatal depression. The risk was strongest when RLS emerged in the third trimester, when evening leg discomfort and sleep disruption are most likely to worsen mood … Read more
Summary: Researchers at the University of Colorado Anschutz have discovered how herpes simplex virus type 1 (HSV-1), the virus commonly responsible for cold sores, reprograms the brain’s resident immune cells. After infection, microglia shift into an interferon-driven antiviral state while reducing the expression of genes needed for routine maintenance and support of neural tissue. These … Read more
Summary: A prospective longitudinal study of 1,035 Israeli adults tracked over six months after the October 7 attacks identifies four clear psychological response patterns to mass trauma: resilience (about 54%), natural recovery after severe early distress (about 27%), chronic distress (about 18%), and delayed onset of symptoms (about 2.5%). The research shows that the way … Read more
Summary: A year-long longitudinal study using gamified smartphone tasks shows that subtle increases in risky decision-making precede rises in alcohol consumption among people with mild to moderate alcohol use disorder (AUD). By measuring month-to-month cognitive and behavioral changes, researchers found that shifts in risk tolerance and information-gathering behavior predicted next-month drinking increases, suggesting a pathway … Read more
Summary: Neuroscientists have mapped how the human brain combines facial expressions and vocal tone to interpret emotion. Rather than keeping visual and auditory signals in separate sensory silos, the brain’s face- and voice-selective regions share overlapping emotional information across senses. Some cortical areas represent the same emotion in a similar neural format whether it is … Read more
Summary: A Penn State study finds that the familiar “pregnancy brain” — the memory lapses, concentration problems, and mental fuzziness reported by many expectant and new mothers — is closely linked to symptoms of anxiety and depression. The researchers discovered that regular physical activity reduced cognitive fog for women with depressive symptoms but, unexpectedly, increased … Read more
