- 1Brain connectivity study sheds light on psychosis heterogeneity▼Connectomic signatures advance the understandings of transdiagnostic heterogeneity in psychosis
A study published in Nature reports connectomic signatures that advance understanding of transdiagnostic heterogeneity in psychosis. The work suggests brain network patterns can help distinguish subtypes of psychotic disorders that cut across traditional diagnostic categories. Researchers say the findings could support more precise diagnosis and targeted treatment approaches for conditions such as schizophrenia.
- 2Are right-brained people really more creative?●Are right‑brained people more creative? Here's what science tells us
A popular science piece examines the widespread belief that creative people are 'right-brained' and logical people 'left-brained'. It looks at what neuroscience actually shows: while the brain's hemispheres specialise in some functions, research finds no evidence that individuals rely on one side, and creativity involves widespread brain networks rather than a dominant hemisphere.

Researchers have unveiled a new atlas mapping the gene networks involved in building the human brain. The resource charts how genes act together during brain development, offering scientists a reference for studying how the brain forms and what goes wrong in neurodevelopmental disorders. It is expected to become a widely used tool for biologists and medical researchers.
- 4Study links chronic back pain to unexpected brain network●Chronic back pain may activate an unexpected brain network, study finds
New research suggests chronic back pain may engage a brain network not previously associated with persistent pain, offering a possible clue to why the condition is so hard to treat. Scientists say the finding could reshape how chronic pain is understood and studied.
- 5Inhibitory Synapses Steer Brain Networks Toward Criticality▼How the Reach of Inhibitory Synapses Steers Brain Networks Toward Criticality
New research reported by Bioengineer.org suggests that the reach of inhibitory synapses—how far inhibitory neurons exert their influence—plays a key role in guiding brain networks toward a critical state. Criticality is believed to optimize information processing in the brain, balancing order and randomness. The findings shed light on how neuronal circuit structure may tune cortical dynamics and support healthy brain function.
- 6Brain's Cleaning System May Help Prevent Alzheimer's●Your Brain Has Its Own Cleaning System That Helps Prevent Alzheimer’s. Science Is Learning How to Repair It
New coverage highlights the glymphatic system, the brain's waste-clearance network that removes proteins linked to Alzheimer's disease, and emerging research into how it can be repaired or enhanced. Scientists are reportedly exploring ways to restore its function, which could open new avenues for preventing or slowing dementia.
- 7Mixture-of-Experts Drives September's Biggest AI Models●Only 3% of the Brain Wakes Up: The Mixture-of-Experts Playbook Behind September's Biggest Models # ai # machinelearning
A new explainer examines the Mixture-of-Experts architecture behind September's largest AI models, drawing on the claim that only about 3% of the brain is active at any moment to illustrate sparse activation. The piece outlines how MoE systems switch on small portions of a network per task, cutting compute while scaling parameters, and why the technique has become central to recent frontier model releases.
