During and after pregnancy, hormones drive profound changes in the brain’s structure and function.

Pregnancy Changes Mothers’ Brains. These Recent Discoveries Are Showing Us How

“Baby brain” isn’t the deficit it’s stereotyped to be, research suggests. Neural adaptations during pregnancy can prime soon-to-be-moms to become more attuned to their children and enhance social cognition

The treatment involves wearing a headset for various at-home sessions.

The Future of Mental Health

FDA-Approved At-Home Brain Stimulation Device Aims to Treat Depression by Changing Patients’ Brain Excitability

The treatment consists of a Bluetooth headset that patients can connect to an app on their smartphones. It could mark a revolution in mental health medicine

Microscope image of a cross-section of a mouse nose. The animal was genetically altered so that its nerve cells used for smell glow green. Some dying nerve cells appear red.

Scientists Create the First Detailed ‘Smell Map’ of Odor Sensors in the Mouse Nose—and Sniff Out Some Surprising Discoveries

In two new studies, researchers used genetic techniques to upend a longstanding assumption that nerve cells with scent detectors were randomly arranged. They don’t know whether the same spatial organization is found in human noses

Undetectable infrasound might explain why some people report paranormal experiences, a new study suggests.

Worried Your House Is Haunted? The Spooky Sensation Might Arise From a Surprisingly Simple Source

Infrasound—noise below the range of typical human hearing—from power, heating and mechanical systems within buildings can make people feel irritated and induce a stress response, according to a new study

More than 50 million people suffer from epilepsy around the world, making it one of the most common and severe neurological disorders globally.

These Young Innovators Have Created a ‘Fitbit’ to Predict Epileptic Seizures

Truman Pierson and Christopher Fitz are developing behind-the-ear EEG patches and an accompanying app that issues an alert if the user is at high risk for a seizure in the next hour

The researchers studied neural activity in 16 participants with epilepsy who had electrodes in their brains.

We Use Many of the Same Brain Cells to See and to Imagine Objects, a Study Suggests. The Findings Provide a New Window Into Memory

While past research has hinted at an overlap in relevant brain regions, the new work drills down to the cellular level. The discovery could help improve treatments for memory disorders, such as dementia, and certain psychiatric conditions, like schizophrenia

Astronauts struggle to adapt to weightlessness, even after months on the International Space Station, a study suggests.

Astronauts’ Memories of Earth’s Gravity May Influence How They Move and Hold Objects, Even After Months in Space

Examining the fine motor skills of space travelers can help improve safety for future missions, scientists say

The hallucinogenic mushroom Psilocybe pelliculosa, which contains psilocybin

How Do Different Psychedelics Affect the Brain? Scientists Analyzed More Than 500 Neural Scans to Find Out

A new study suggests that four psychoactive compounds work in surprisingly similar ways, and that they break down the separation between how we think internally and how we perceive the outside world

Becoming an expert birder might support brain health, according to a new study.

Becoming an Expert Birder Can Reshape Your Brain and Might Help Protect It From Aging, New Research Suggests

Compared with novices, seasoned birders had denser, more structurally complex brain regions involved with tasks like object identification, visual processing, attention and working memory

In a first for small-brained animals, the study found that bumble bees can keep track of a beat even as it speeds up and down. 

Despite Their Tiny Brains, Bumblebees Have a Surprising Sense of Rhythm, According to a New Study by Neuroscientists

By speeding up the tempo of alternating flashing lights, the scientists were able to demonstrate yet another example of the small insect’s remarkable mind

While the cells can play the game, they’re not very good at it.

A Clump of Human Brain Cells on a Computer Chip Learned to Play the Nostalgic Video Game ‘Doom’

The technology could one day help researchers develop drugs and tailor treatments to individual patients

The perception of sleep is just as important as the quality of sleep.

Vivid Dreams Might Be Key to Feeling Well Rested When You Wake Up, According to a New Study

The findings could help explain the purpose of dreams and help physicians better treat people with sleep disorders

Two participants tried the device, which translates thoughts of specific finger movements into strokes on a virtual keyboard. 

An Experimental Brain Implant Allows People With Paralysis to Type Their Thoughts With Their Minds

One of the two participants wrote words up to a speed similar to an able-bodied person texting on a smartphone

Rats and other rodents have front teeth that grow continuously, so they gnaw to keep them healthy and in shape. 

Rodents Don’t Gnaw Just to Trim Their Teeth—It Also Feels Good, According to a New Study

The findings could help humans who grind their teeth or clench their jaws

Yaks on the Tibetan Plateau have adapted to deal with high-altitude conditions.

This Genetic Mutation Helps Yaks Survive at High Elevations. It Could Lead to Treatments for Nerve Damage in Humans

Animals that dwell at high altitudes have adapted to cope with low oxygen levels, a condition that damages a vital part of nerve cells

A donated super-ager brain

Some People Keep Razor-Sharp Minds Into Their 80s and Beyond. A New Study Reveals Their Secrets

“Super-agers” seem to produce more new nerve cells in a brain region important for memory than other people their age

Despite its growing popularity, ADHD coaching has not been well-studied.

As ADHD Coaching Gains Popularity, Researchers Stress the Importance of Careful Vetting

A recent survey highlights variation in the training credentials and experience across the burgeoning industry, which is mostly unregulated and unlicensed

Researchers asked participants, at an average of about 80 years old, to report their exposure to intellectual enrichment throughout their lives, and then tracked them for around eight years.

Lifelong Learning Might Lower Your Risk of Developing Alzheimer’s Disease, a New Study Suggests

While the research does not point to a direct, causal link, it hints that activities like reading, writing and playing games might help extend cognitive function

By age 20, autism diagnoses are almost equal among men and women in Sweden, a new study suggests.

Is Autism Really a Male-Dominated Condition? A New Study Suggests Women Have It Just as Often, but Are Diagnosed Later in Life
