Sex differences in the adolescent brain

Sleep EEG evidence of sex differences in adolescent brain maturation.

STUDY OBJECTIVES The steep decline in slow-wave (delta) electroencephalogram (EEG) intensity across adolescence is a prominent feature of late brain maturation. As a first step in determining whether the adolescent delta decline is similar in both sexes, we compared cross-sectional sleep EEG data from 9- and 12-year-old boys and girls. DESIGN All-night EEG recordings, 6 months apart, were con...

Sex differences in the brain.

Sex differences in adolescent white matter architecture.

BACKGROUND Sex-specific trajectories in white matter development during adolescence may help explain cognitive and behavioral divergences between males and females. Knowledge of sex differences in typically developing adolescents can provide a basis for interpreting sexual dimorphisms in abilities and actions. METHOD We examined 58 healthy adolescents (12-14years of age) with diffusion tensor...

Oversimplifying Sex Differences in the Brain

Sex differences in the emotional brain.

In this issue, Schienle et al. use brain imaging to examine emotion-related activation differences between men and women. Are those differences related to the way the sexes feel emotions? Are they hardwired? In this commentary, we briefly review sex differences in feeling, perception of emotionally evocative cues, and expression of emotions, and we discuss how they may be related to sex differe...
