Brainless upside-down jellyfish, like this one in its natural habitat near Eilat, Israel, spend about one-third of their time asleep.

Even Though They Don’t Have Brains to Rest, Jellyfish and Sea Anemones Sleep Like Humans

Sleep may have evolved to help reduce DNA damage in nerve cells long before they became centralized in the brain, a study suggests

Stimulants prescribed for ADHD target the parts of the brain related to wakefulness and reward, shown in yellow and orange, according to a new study.

How Do These ADHD Medications Work in the Brain? The Mechanisms Are Different Than Once Thought, a Study Suggests

Adderall, Ritalin and other stimulants prescribed for attention-deficit/hyperactivity disorder seem to work on brain areas involved with wakefulness and reward, rather than attention

Pigeons can sense magnetic fields via their inner ears, new research suggests.

Pigeons Rely on the Earth’s Magnetic Field to Navigate. Now, Researchers May Have Uncovered How They Do It

The vestibular system, a set of structures in the inner ears that helps with balance, may grant the birds their special ability

Researchers studied thousands of brain scans to see how the organ's architecture changes over a lifetime.

Your Brain Goes Through Five Distinct Epochs of Neural Wiring During Your Lifetime, New Research Suggests

These eras of brain architecture are marked by four major turning points, which occur around the ages of 9, 32, 66 and 83, according to a new study

New research suggests multilingualism may slow cognitive aging. 

Neuroscientists Studied More Than 80,000 People and Found That Speaking Multiple Languages Might Slow Down Brain Aging

An enormous analysis of data from a broad array of participants found an association between multilingualism and cognitive aging

New research strives to understand what happens in the brain at the transitions between sleeping and being awake.

At the Mysterious Boundary Between Waking Life and Sleep, What Happens in the Brain?

Neuroscientists studying the shifts between sleep and awareness are finding many liminal states, which could help explain the disorders that can result when sleep transitions go wrong

Researchers found an association between moderate step counts and slower cognitive decline among people at risk of developing Alzheimer's. 

A Short Walk in the Park Might Slow Cognitive Decline in People at Risk of Developing Alzheimer’s

New research indicates that even moderate step counts, as low as 3,000 steps daily, were linked with delayed symptom onset

A new study investigates addiction-like behaviors in dogs.

Does Your Dog Love Chasing a Ball? Study Suggests Dog Toy ‘Addiction’ Is Real

The research documents addiction-like tendencies in canines, offering scientific evidence that appears to support owners’ own observations

The researchers found that tango is especially good at slowing brain aging. 

Creative Hobbies Like Tango Dancing or Playing Musical Instruments May Help Keep Your Brain Young, Study Finds

Scientists discovered that talented experts had “younger” brains than those of their less experienced counterparts, and even those who only dabbled in creativity reaped benefits

People with a rare form of epilepsy have reported feelings of bliss just before having a seizure. A French Swiss neurologist has pinned down where this “aura” originates in the brain in hopes that one day, that feeling might be reproduced non-invasively in others.

Some People Experience Blissful Ecstasy Right Before a Seizure. Could Understanding This Feeling Help Treat Depression?

A neurologist shares her thoughts and research about “ecstatic epilepsy” in a wide-ranging conversation on how we perceive the world—and create the world we perceive

A sea lamprey shows off its nightmarish mouth.

This Invasive Vampire Fish Is Helping Researchers Understand the Human Nervous System in Jaw-Dropping Ways

The sea lamprey looks like it’s from another planet, but this ancient creature has a surprising amount in common with humans

Huntington's disease gradually damages the caudate nucleus, pictured in red. 

Experimental Gene Therapy Successfully Treats Huntington’s Disease for the First Time

Preliminary results from a small study offer hope for treatment of the degenerative disease

Stuttering affects roughly 1 percent of the world's population, yet it is not well researched.

What Causes Stuttering? A Large DNA Analysis Study Offers New Clues, Uncovering Links to 48 Genes

Scientists analyzed data from more than one million users of 23andMe and found associations between certain genes and stuttering

A healthy volunteer takes the Fastball test in his home alongside lead researcher George Stothart.

Three-Minute Take-Home Test May Identify Symptoms Linked to Alzheimer’s Disease Years Before a Traditional Diagnosis

Researchers say the experimental tool has huge implications for public health, especially in conjunction with Alzheimer’s drugs that are most effective in the disease’s early stages

Subtly different brain areas light up in response to viewing certain colors, a new study suggests.

Do We See the Same Colors as Others? Study Suggests Brains Respond to the Same Hues in Similar Ways

Using MRI scans, researchers found that participants’ patterns of brain activity were alike when looking at certain colors. But people can still experience those colors differently

New Helmet-Shaped Device Could One Day Treat Conditions Such as Parkinson’s Without Invasive Surgery, Scientists Suggest

In a first-of-its-kind achievement, researchers non-invasively and precisely directed ultrasound beams to target a location deep within the brain

A new study tested a device trained to translate four participants' inner thoughts.

Science Fiction? Think Again. Scientists Are Learning How to Decode Inner Thoughts

A brain-computer interface has gotten better than ever before at translating thoughts from people with speech difficulties. Researchers are also thinking through how to protect users’ privacy

The study found that regular exercise, along with other lifestyle changes, can slow cognitive decline in older adults.

Cognitive Decline Can Be Slowed Down With Lifestyle Changes, From Diet to Exercise and Social Time, New Study Suggests

A 2,100-participant clinical trial found that structured and self-guided lifestyle changes can improve cognitive capabilities in older, at-risk adults

Seeing a potentially infectious person might kickstart the body's immune system, according to a new study.

The Mere Sight of Someone Sick Triggers an Immune Response, Study Suggests

Researchers equipped study participants with virtual reality headsets and observed how their brains and immune systems reacted to avatars with signs of illness

Until recently, jokes were thought to be beyond the reach of A.I.

Can Artificial Intelligence Learn the Nuances of Human Humor?

As people turn to A.I. for therapy and companionship, some say the models still leave something to be desired
