Researchers say that CTE is very preventable, since less than 1 percent of brains from the general public show signs of it.

Three in Four Former NFL Players Who Died From 2008 Through 2023 May Have Had CTE, a Brain Disease Caused by Repeated Head Injuries

The researchers also estimate that around one in four of the former football players had dementia, a common feature of late-stage CTE

Two crows performed a task in which they determined whether dots were moving to the left or right of a screen. Some of the dots moved in random directions as a distraction.

Crows Can Make Decisions Based on Visual Information at Lightning Speed—Roughly Twice as Fast as Humans Can, Study Suggests

Even though the brain structures of birds and mammals are different, a new study suggests that crows and primates have similar decision-making nerve cell circuitry

Third place: neurons in an expanded mouse brain

See the Scientific and the Mundane Become Surprisingly Dazzling When Viewed Through a Microscope, From Neurons to Ballpoint Pens

The Nikon Small World Competition has announced its photography winners for its 52nd annual contest. This comes weeks after its video winner was dethroned for use of generative A.I.

Most previous brain-computer interfaces have focused on speech or movement, rather than both simultaneously.

This Brain Implant Allows People With Paralysis to Speak and Gesture at the Same Time Via a Mind-Controlled Virtual Avatar

The experimental technology is still in the early stage and was fully tested in just two participants. But it could one day help people with motor problems communicate with more nuance or help them control robotic prosthetic limbs

Optogenetics works like a precise, light-controlled switch for nerve cells in the brain.

Trio of Scientists Wins Medicine Nobel for a Method to Turn Nerve Cells On and Off With Light, Helping to Unravel the Brain’s Mysteries

Karl Deisseroth, Peter Hegemann and Georg Nagel received the 2026 award for their contributions to a revolutionary technique in neuroscience called optogenetics, which allows researchers to examine precise connections between neuronal activity and behavioral outcomes in live animals

MRI scanners create detailed images of the inside of the body using a powerful magnet and radio waves.

MRI Scans Might Reveal Signs of Alzheimer’s Disease Seven Years Before a Telltale Marker Appears in the Brain

Not all researchers are convinced that the brain changes detected via MRI are robust enough to become a diagnostic tool. But the findings could help researchers better understand the mechanisms that drive the neurodegenerative disease

A new review emphasizes associations between reading engagement and benefits such as better cognitive performance.

From Boosting Mental Health to Reducing Dementia Risk, Here’s Why Reading Is Extremely Good for You, According to Science

Mounting evidence suggests that regularly cozying up with a book can increase brain and mental health, improve literacy and math skills, and even slow cognitive decline. What’s more, fiction seems to have the added benefit of introducing readers to others’ perspectives

Using their new knowledge, the researchers became the first to successfully coax human stem cells into becoming hindbrain motor nerve cells.

Scientists Say the Human Brain Might Be Made of Two Distinct Nervous Systems That Got Squished Together

Two separate types of progenitor cells give rise to the front and back of the organ, according to a new study. The findings can help researchers study human diseases that affect the hindbrain, since its nerve cells have previously been difficult—if not impossible—to make in the lab

Researchers looked at changes in the volume of gray matter, which is made mostly of nerve cell bodies and located in the brain's wrinkly outer layer.

The Brain Shrinks as We Age and During Major Transitions. But Surprisingly, It Seems to Take a Break From Rewiring During Menopause

Puberty, pregnancy and menopause are the three major hormonal transitions for the female brain. Researchers already knew that during the first two, the organ fine-tunes itself in response to hormonal shifts, but they haven’t been sure about the third

A side view of a "xenocortical" mouse brain, with the grafted human tissue seen in green and red.

Scientists Created Mice With Half-Human Brains. The Hybrid Animals Could Revolutionize Our Understanding of Neurological Disorders

Our brains and their associated diseases are notoriously hard to study. So researchers developed an animal model with a cortex—the brain’s outer layer—grown from human-derived cells

This New Brain Map Shows Every Nerve Cell in an Adult Male Fruit Fly’s Central Nervous System. Here’s Why That Matters

The recently released “connectome” joins a previously completed map of an adult female fruit fly’s brain. The digital 3D diagrams allow scientists to trace precise neural paths in the bugs’ brains, which can unlock secrets about the organ in humans

Schizophrenia is difficult for psychiatrists to diagnose. Can artificial intelligence help do it better?

Could Artificial Intelligence Help With Early Diagnosis of Schizophrenia?

The tool may pick up subtle differences in the speech of people with the mental health condition better than human psychiatrists

The researchers trained pet dogs to sit still during an MRI scan.

Scientists Gave Dogs MRIs and Learned That They’re Surprisingly Good at Distinguishing Between Human Emotions, Even Some Negative Ones

A recent study found that man’s best friend processes positive and negative human emotions differently and can distinguish between fearful faces and those showing sadness or anger

Scientists have discovered more than 4,400 ancient preserved human brains, some of which are 12,000 years old.

Archaeologists Have Found Thousands of Intact Ancient Human Brains. Scientists Say They’ve Figured Out Why the Organs Don’t Always Rot

Under the right conditions—wet and oxygen-deprived—the same chemical reactions that cause tissue to break down can instead have the opposite effect, according to a new study

Past studies have suggested that what’s good for the heart may also help protect the brain. But researchers hoped to frame that connection in a different way—not just as reduced risk, but as time gained without dementia.

Avoiding These Three Vascular Health Risk Factors in Midlife Can Help You Delay Dementia for About 13 Years, Study Suggests

High blood pressure, diabetes and smoking are three major modifiable risk factors of dementia. New research tracked more than 12,000 participants to quantify how many years of healthy cognitive function you can gain by evading some or all of them during middle age

The belly is one of the most ticklish body parts across analyzed cultures.

From Armpits to Feet, Our Ticklish Hot Spots Are Surprisingly Universal. The Finding Offers Clues About the Sensation’s Evolutionary Origins

A new study probes the basics of gargalesis, a poorly understood type of tickling caused by firm, repetitive touches that typically elicits laughter and squirming

The mushroom Psilocybe pelliculosa is one of several species that produce psilocybin, a natural compound with hallucinogenic properties.

Could Psilocybin Help Treat Anorexia? A Small Clinical Trial Suggests the Psychedelic May Make Patients More Open to Recovery

The drug, paired with intensive psychological support, may loosen the rigid patterns of thought associated with the eating disorder, scientists say—but they caution that it is not a magic cure

The new work contributes to a broader shift in bilingualism research, which is moving toward the view that grammar is supported by a shared, flexible brain mechanism that operates across all languages.

How Does a Bilingual Speaker’s Brain Process Two Languages? New Research Suggests That Both Rely on the Same Neural Wiring

Scientists have long wondered whether different neural mechanisms govern each language within a bilingual speaker’s brain. A recent study of people who speak both English and Spanish hints at a single “grammatical engine”

The drug targets the tau protein, which accumulates and forms tangles (seen in blue) in nerve cells.

Experimental Alzheimer’s Drug That Fights a Tough-to-Target Protein Shows Promise at Slowing Cognitive Decline in a Clinical Trial

Recently FDA-approved treatments work to clear clumps of the protein amyloid beta in the brain. A drug that instead goes after tangles of the protein tau can yield similar cognitive outcomes, a new study suggests

A pregnant naked mole-rat queen, on the left, and a worker, on the right, sniff each other.

Naked Mole-Rat Queens Emit a Special Scent to Stop Their Rivals From Reproducing, a New Study Suggests

The strange-looking creatures are one of two known mammals that use a social structure like that of bees and ants. A ruling rodent maintains power over her colony via one key chemical compound, according to new research
