Crows make decisions twice as fast as humans and monkeys

Crows make visual decisions in 235 milliseconds, study finds

Two carrion crows chose a moving-dot direction in 235 milliseconds on average.
The birds remained better than chance on difficult visual trials and approached 100% accuracy with clear signals.
Neural activity for the alternative choices began to diverge about 70 milliseconds after stimulus onset.

An Ancient Virus Explains Why the Human Brain Is Special

Ancient Retrovirus May Have Shaped Human Brain Divergence

Researchers studied PTERV1, an endogenous retrovirus family found in chimpanzees, bonobos and gorillas but absent in humans.
Chimpanzee-specific PTERV1 insertions on chromosome 19 were linked to silencing of LINC00662 in brain organoids.
The work identifies a possible regulatory mechanism in human-chimpanzee brain divergence, not a single-cause explanation for human cognition.

Blood test can help clinicians better identify brain injury severity in patients

Blood Biomarkers Could Improve TBI Triage Beyond CT

Researchers reported clinical cutoffs for two brain-associated proteins detected in blood after traumatic brain injury.
The approach is meant to complement CT scans and improve patient identification and triage.
TRACK-TBI findings previously showed functional limitations at one year in more than half of participants with mild brain injury.

Genetic tools point to division of labor among the brain's astrocytes

Genetic tool finds specialized roles for brain astrocytes

A Nature study used a genetic tool to separate astrocyte subtypes in mice.

Scientists discover a natural compound that could protect the brain from too much salt

Soy Compound LPC70 Shows Promise Against High-Salt Harm in Mice

LPC70 is a soy-derived form of lysolecithin.
In mice, it was associated with lower blood pressure during a high-salt diet.
The study also reported better memory and social behavior in treated mice.
The result is preclinical and does not establish a treatment for people.

Scientists discover how deep sleep builds muscle, burns fat, and boosts the brain

Study Maps Brain Feedback Loop Between Deep Sleep and Growth Hormone

Researchers identified neurons that regulate growth hormone release during sleep.
The study describes a two-way feedback loop: sleep stimulates growth hormone, which also influences wakefulness.
The work may guide future research into sleep, metabolic and neurological disorders.

What a worm's brain can teach us about sex differences in the nervous system

Worm brain study probes sex differences in neural activity

Male and hermaphrodite C. elegans differ in neuron counts and in observed brain activity.
Researchers tested responses to controlled cues including food odors and danger-related chemicals.
The work may help examine links between sex-specific neural activity, behavior, reproduction and aging.

Brain cells meant to protect us may be fueling cognitive decline

Myelin-Making Brain Cells May Help Drive Cognitive Decline

The study used data from the Lothian Birth Cohort 1936, plus human tissue and mouse experiments.
Researchers found that age-related cell dysfunction can lead to abnormal myelin production.
Existing drugs acting on the pathway warrant research, but no treatment conclusion has been established.

Mysterious brain activity under anesthesia challenges what we know about consciousness

Brain Signals Under Anesthesia Reveal Language Processing

Researchers recorded hippocampal activity during epilepsy surgery under general anesthesia.
Neuropixels probes monitored signals from hundreds of individual neurons.
The brain analyzed language, recognized word types and predicted upcoming words.
The work distinguishes sophisticated processing from conscious awareness.

Chronic Back Pain Flares Linked to Brain Network

The study used fMRI to examine 114 adults with chronic lower back pain.
Movement-induced pain flares were associated with increased default mode network activity.
The finding is associative and does not establish a cause of chronic pain.

LSD microdosing shows potential sustained attention gains in women, but none in men

LSD Microdosing Pilot Finds Different Attention Effects by Sex

The randomized controlled pilot involved 48 healthy volunteers and four 15-microgram doses of LSD over two weeks.
Women receiving low-dose LSD responded about 8% faster on a sustained-attention task than in the placebo condition.
The result was not seen in men and remains preliminary; it does not establish a treatment benefit.

Study finds positive parenting teaches children how to experience joy—and could lead to better mental health

Early Positive Parenting Linked to Adolescents’ Joy Responses

The study links parenting during preschool years with how children experience joy and satisfaction through adolescence.
Researchers describe the connection as involving a major neural indicator of mental-health risk.
The findings are associative and point to prevention research, not a diagnostic tool or guaranteed outcome.

Intensive breathing linked to altered consciousness and brain communication

Intensive Breathwork Alters Brain Blood Flow and Networks

A 30-person MRI study examined experienced high-ventilation breathwork practitioners.
Gray-matter cerebral blood flow fell by about 45% on average during sessions.
Stronger altered-state reports tracked with default mode network changes.
Researchers say controlled trials are still needed to assess therapeutic potential.

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.
