Study reveals new clues to sex differences in autism

It is well established that autism occurs much more frequently in boys than in girls, and that girls seem to have a greater resilience to developing the condition. It has been unclear, however, why that is.

Study sheds light on how autism manifests in the brains of girls

New research has shed light on how autism-spectrum disorder (ASD) manifests in the brains of girls, prompting the scientists to warn that conclusions drawn from studies conducted primarily in boys should not be assumed to hold true for girls.

Signal detection theory can be used to better understand cognitive fatigue

A team of New Jersey researchers has shown that changes in perceptual certainty and response bias, two central metrics of signal detection theory (SDT), correlate with changes in cognitive fatigue.

Study measures language-skill improvement by tracking brain activity

A study with first-time learners of Japanese has measured how brain activity changes after just a few months of studying a new language. The results show that acquiring a new language initially boosts brain activity, which then reduces as language skills improve.

Anabolic-androgenic steroids can have deleterious effects on the brain

Anabolic-androgenic steroids (AAS), a synthetic version of the male sex hormone testosterone, are sometimes used as a medical treatment for hormone imbalance. But the vast majority of AAS is used to enhance athletic performance or build muscle because when paired with strength training.
