Summary: A major challenge in schizophrenia is the loss of cognitive flexibility—the capacity to revise beliefs when new evidence appears. New research from MIT pinpoints a mutation in the grin2a gene that disrupts a thalamocortical circuit responsible for this “reality check,” causing the brain to over-rely on outdated beliefs and ignore incoming sensory information. The … Read more

Summary: For years the “psychedelic renaissance” has suggested that substances like psilocybin and LSD could transform mental health care and surpass conventional antidepressants such as SSRIs. A new, rigorous analysis from researchers at UCSF, UCLA, and Imperial College London offers a more tempered picture: when patients know which treatment they receive, psychedelic-assisted therapy does not … Read more

Summary: Working memory acts as a mental scratchpad, allowing us to hold and manipulate information in real time. A new study identifies a precise molecular pathway centered on the protein Munc13-1 that functions as a gatekeeper for this process. The research shows that working memory requires synapses to transiently strengthen their connections through calcium-dependent signaling. … Read more

Summary: Many people instinctively close their eyes to hear faint sounds more clearly. New research shows that in noisy environments this habit can be counterproductive: closing your eyes can push the brain into a mode that over-filters incoming sounds, making it harder to detect the very signals you’re trying to hear. Using electroencephalography (EEG) to … Read more

Summary: Schizophrenia and related psychotic disorders are frequently preceded by silent brain vulnerabilities that appear long before overt symptoms such as hallucinations or delusions. A major new study points to the glymphatic system—the brain’s internal waste-clearance pathway—as a possible contributor to that early vulnerability. Researchers studying people with 22q11.2 deletion syndrome, a genetic condition that … Read more

Summary: Researchers have long known that vision has a rapid, subconscious route to the brain’s fear center that helps us react to visual threats. New research now indicates a similar fast-track exists for sound: an auditory pathway that connects hearing regions directly to the amygdala, the brain’s fear hub. This pathway helps explain why we … Read more

Summary: For people with severe paralysis who cannot speak or move their hands, loss of communication is a profound loss of independence. A new investigational brain-computer interface (iBCI) translates the brain’s intent to move fingers into typed words, restoring fast and accurate text communication. Researchers report an implantable neuroprosthesis that maps attempted finger movements onto … Read more

Summary: Have you ever felt your attention briefly slip during a dull or repetitive task, as if a small part of your brain “turned off” for an instant? New research shows these micro-lapses reflect sleep-like brain activity that can occur while we are awake. These so‑called “local sleep” events are common when people are tired, … Read more

Summary: Scientists have developed a bio-upcycling method that converts plastic waste into L-DOPA, the primary medication used to treat Parkinson’s disease. Researchers engineered strains of E. coli to transform polyethylene terephthalate (PET) — the plastic commonly found in beverage bottles and food packaging — into a high-value therapeutic compound. This work demonstrates the first engineered … Read more

Summary: Researchers have identified a central coordination mechanism in the brain that reshapes how we think about chemical imbalances. A new study shows that in the striatum — a key region for movement and learning — acetylcholine not only works alongside serotonin but can directly drive serotonin release, effectively “taking the wheel.” Specialized neurons called … Read more
