How to make a mouse smell a smell that doesn’t actually exist
The ability to create a perception might lead to a deeper understanding of how the brain makes sense of the world.

The way the coronavirus messes with smell hints at how it affects the brain
Conflicting reports offer little clarity about whether COVID-19 targets the brain.

A new 3-D map illuminates the ‘little brain’ within the heart
Microscopy and genetic studies yield a comprehensive map of the nerve cells found in the heart of a rat.

How coronavirus stress may scramble our brains
The pandemic has made clear thinking a real struggle. But researchers say knowing how stress affects the brain can help people cope.

Blind people can ‘see’ letters traced directly onto their brains
Arrays of electrodes can trace shapes onto people’s brains, creating bursts of light that people can “see.”

A game based on Simon shows how people mentally rehearse new information
Signs of learning echo through people’s resting brains.

‘The Idea of the Brain’ explores the evolution of neuroscience
Despite advances, much about the human brain is still a mystery, a new book shows
- Neuroscience
Mice’s facial expressions can reveal a wide range of emotions
Pleasure, pain, fear and other feelings can be reflected in mice’s faces, sophisticated computational analyses show.
- Genetics
Squid edit their genetic material in a uniquely weird place
Some squids’ seeming ability to edit RNA on the fly could help scientists develop a technique much like the DNA-editing tool CRISPR, but for RNA.
- Artificial Intelligence
An AI that mimics how mammals smell recognizes scents better than other AI
An artificial intelligence modeled after the neural circuitry in mammalian brains can keep learning new aromas without forgetting others.

New electrodes can better capture brain waves of people with natural hair
Electrodes weren’t designed for people with thick, curly hair. A redesign is needed, says engineer Pulkit Grover.

Brain waves common during sleep also show up in awake sheep
Sleep spindles, thought to help solidify memories in people, may do similar work during wakefulness if these daytime ripples occur in humans.
