Getting a head start on autism

Early diagnosis followed by early treatment may reduce autism’s impact on kids — and help them to communicate better.

Brain

Autism unlocked

Experts are learning how to diagnose this brain disorder in infancy. That may be early enough to allow nerve cells in the brain to develop new connections — ones that form detours around autism-affected areas.

Mapping the brain’s highways

A new map may explain why some brain injuries are worse than others. Even relatively minor injuries that disrupt message superhighways may have a more devastating impact than some seemingly catastrophic injuries.

When Cupid’s arrow strikes

Scientists have begun dissecting what it means to be in love. They are finding that much of what we feel can be explained by the effects of a few key chemicals — and not just on our hearts and brains, but on our whole bodies.

The weight of thought

Thinking heavy thoughts? Scientists have just put people on a balance and shown that the brain briefly gains blood — becoming a bit heavier — while concentrating.

Memory lessons from a forgetful brain

Scientists have just begun probing the preserved tissue from “H.M.” Even five years after he died, this man’s brain continues to offer lessons on how people make — or fail to make — memories.

Erasing memories

Electroconvulsive therapy is used to treat severe depression, but the electrical jolt it sends into the brain also may erase bad memories.

Inheriting fear

Scared of something and don’t know why? Maybe your parents or grandparents passed along their fear to you, a new mouse study suggests.

Seeing without light

Many people report seeing their own hands moving in the dark, a new study finds. In these people, brain areas responsible for motion appear to fool vision centers into seeing what they would have — if there had been enough light to do so.

Fear prompts teens to act impulsively

A new study finds that teens may act impulsively in the face of fear. This might help explain high rates of violence among such adolescents, the authors say.
