Fruit fly study reveals how neural gates switch on short-term memory

Fruit Fly Study Reveals How Neural Gates Switch On Short-Term Memory

A study led by NYU Langone Health in fruit flies confirmed a long-standing suspicion about how the brain encodes short-term memories.
The research was published online October 7 in the journal Nature, with Katherine Nagel as senior investigator.
Flies exposed to apple cider vinegar moved toward the odor and kept going for seconds after it disappeared, showing the memory persisting.
Brain monitoring revealed two different neuron types responding to the smell with similar patterns of activity, forming a gate.

Does your sleep tracker get it right? A neuroscientist weighs in

Sleep Tracker Accuracy: A Neuroscientist on What Wearables Miss

A 2025 meta-analysis of 24 studies and nearly 800 participants found wearables overestimate total sleep time by about 17 minutes per night compared with polysomnography.
The main blind spot is quiet wakefulness: lying still and awake is often misinterpreted as sleep, which disproportionately affects people with insomnia.
Wearables do not measure brain waves directly, so sleep-stage estimates (REM, deep sleep) are inferred from movement and heart rate rather than measured clinically.
Apple's newest watch introduces a morning readiness score and claims the most accurate heart-rate tracking, but these claims have not been independently verified.

2026 Nobel Prize in Medicine awarded for brain research tool called optogenetics

2026 Nobel Prize in Medicine Awarded for Optogenetics, the Brain Research Tool

Karl Deisseroth, Peter Hegemann and Georg Nagel share the 2026 Nobel Prize in Physiology or Medicine.
The citation honors their discoveries concerning light-gated ion channels and optogenetics.
Optogenetics lets researchers switch specific neurons on or off using light, giving causal control over brain circuits.
The prize recognizes an enabling research tool rather than a single drug or disease mechanism.

US-German trio wins medicine Nobel for work on optogenetics

US-German Trio Wins 2026 Medicine Nobel for Optogenetics

The 2026 Nobel Prize in medicine was awarded to U.S. psychiatrist and neurologist Karl Deisseroth and German researchers Peter Hegemann and Georg Nagel.
The award recognizes optogenetics, a field that helps researchers understand how specific cell types contribute to behaviors such as learning, fear, addiction and movement.
The Nobel Assembly said optogenetics has fundamentally altered understanding of the brain and could one day lead to treatments for conditions including Parkinson's disease and epilepsy.
Researchers are using the method in clinical attempts to restore sight in people with visual impairment.

Newly discovered hair cells on squid may offer clues to understanding hearing loss in humans

Squid Hair Cells Found Across Entire Body, Offering Clues to Human Hearing Loss

Case Western Reserve University researchers found that squid have hair cells lining their entire body surface, not only their heads and arms.
The study, published in Current Biology, includes the first full-body mapping of lateral lines on squid, the arrays formed by hair cells.
The team used light sheet microscopy, which illuminates one plane at a time to build 3D images while limiting tissue damage.
Part of the research was conducted at the Marine Biological Laboratory in Woods Hole as part of a three-year fellowship on how squid hear.

Brain area discovered that may be critical for viable pregnancies | New Scientist (via www.newscientist.com)

Newly Discovered Brain Area May Be Critical for Viable Pregnancies

A previously unknown brain region appears essential for successful embryo implantation in mice, per New Scientist.
The finding may help explain why some pregnancies and IVF attempts fail.
Implantation — when a fertilised egg attaches to the uterine lining — is a key bottleneck in early pregnancy.
The work is in mice; whether an equivalent region exists or functions similarly in humans is unknown.

Cocaine plays with mind, hijacks brain circuit, drives repetitive behavior

Cocaine Hijacks Brain Circuit, Driving Rigid and Repetitive Behavior

Reporting indicates cocaine hijacks a brain circuit, driving increasingly rigid and repetitive behavior.
Cocaine's known action on dopamine signaling exaggerates reward learning and recalibrates motivation around the drug.
Behavior shifts from flexible, goal-directed control toward automatic habit loops that are hard to interrupt.
The finding supports viewing addiction as a circuit-level hijacking rather than a simple failure of willpower.

Brain-mapping framework reveals shifts in information flow during pain and movie watching

New brain-mapping framework tracks information flow during pain and movies

Researchers at the Institute for Basic Science in South Korea, Sungkyunkwan University and other institutions developed a neuroimaging analysis framework called integrated effective connectivity (iEC).
The approach aims to estimate how activity in one brain region influences activity in another, moving beyond the statistical associations produced by conventional fMRI analysis.
The work, published in Nature Neuroscience, includes a signal flow hierarchy map for the resting brain.
The team produced functional hierarchy maps for three states: movie watching, resting and tonic pain, and tracked state-dependent changes in hierarchy levels.

Autism-risk mutations reveal two opposing patterns of brain gene activity | EurekAlert! (via www.eurekalert.org)

Transcriptome-Based Classification Maps Autism Risk Mutations in Mice

Science published "Transcriptome-based classification in mice with ASD-risk mutations" in Volume 393, Issue 6817, pages 1250–1257 (September 2026).
The method groups mice by gene-expression profiles instead of by the specific autism-risk mutation they carry.
Transcriptomes reflect both genetic variation and environmental influence, offering a dynamic readout of biological state.
Mouse models permit controlled, developmentally precise profiling but cannot directly translate to human diagnosis or treatment.

Our brain evolved from two primitive nervous systems that merged | New Scientist (via www.newscientist.com)

Human Brain May Have Evolved From Two Merged Nervous Systems

The front and back of the human brain are built from different progenitor cell populations in the embryo, according to New Scientist.
That developmental split suggests the two regions evolved as separate entities rather than as one uniform organ.
The finding implies the brain may be a composite of two primitive nervous systems that later merged.
Anterior and posterior brain regions already show clear functional differences, which the split origin may help explain.
