Pubertal timing is a critical dimension of adolescent brain vulnerability

This study examines how pubertal timing affects adolescent brain vulnerability by analyzing brain hierarchy changes before and after the pandemic.

A broken power-law model of heart rate variability spectra in sleep

This paper introduces a broken power-law model to describe heart rate variability spectra in sleep, finding age, sex, and sleep stages affect spectral characteristics.

Spectral features of heart rate variability in Williams syndrome during sleep

This study analyzes HRV spectral features in Williams syndrome during sleep, finding altered fractal properties and associations with sleep structure indicators.

Conflicting binocular input triggers inhibition followed by rebound, explaining paradoxically fast reaction times

The paper investigates how conflicting binocular visual signals affect perceptual detectability and reaction times, finding a two-phase process of suppression followed by rebound.

The contributions of biological maturity and experience to fine motor development in adolescence

This study examines how biological maturity and experience affect fine motor skills in adolescents, finding that bone age strongly predicts sequential motor performance, while chronological age and musical experience also play roles.

Aperiodic neural activity distinguishes between phasic and tonic REM sleep

This study differentiates phasic and tonic REM sleep states using aperiodic neural activity slopes, showing phasic states have steeper low-band and flatter high-band slopes, and EM amplitudes correlate with these slopes.

Visual training induced occipital fast sleep spindle clustering in humans revealed by full-night HD-EEG recordings

This study shows that visual training increases fast sleep spindle density and clustering in young adults, with no age-related differences.

Navigating Pubertal Goldilocks: The Optimal Pace for Hierarchical Brain Organization

This study examines how the pace of pubertal maturation affects brain organization by linking skeletal age stages to resting-state EEG entropy production.

Scale-free and oscillatory spectral measures of sleep stages in humans

The paper analyzes sleep EEG spectra using the FOOOF method to separate aperiodic and oscillatory components, finding sleep stage-specific spectral features.

Visual imagery vividness declines across the lifespan

The paper examines how self-reported visual imagery vividness changes across age groups, finding a decline from adolescence to middle age.

Topographical relocation of adolescent sleep spindles reveals a new maturational pattern of the human brain

The paper examines adolescent sleep spindle topography and finds a shift from central to posterior regions for fast spindles, suggesting an anterior-to-posterior maturation pattern.

Dissociating experience-dependent and maturational changes in fine motor function during adolescence

This study examines how experience and maturation influence fine motor skills in adolescents, showing task complexity affects experience-driven improvements while simple tasks are shaped by maturation.

Alternative female and male developmental trajectories in the dynamic balance of human visual perception

The paper investigates age and sex-specific developmental trajectories in binocular rivalry, using computational modeling to quantify changes in perceptual stability, sensitivity, and exploration across the lifespan, and reports atypical patterns in autism and borderline personality disorder.

The adolescent pattern of sleep spindle development revealed by HD-EEG polysomnography

This study uses HD-EEG polysomnography to analyze sleep spindle development in adolescents, finding age-related changes in frequency, amplitude, duration, and density, with gender differences in the oldest age group.

Sleep spindle frequency: overnight dynamics, afternoon nap effects, and possible circadian modulation

The paper analyzes sleep spindle frequency dynamics across overnight sleep and naps to assess circadian modulation and age-related changes.

Skeletal maturity predicts cognitive abilitiesin human adolescents

This study shows that skeletal maturity, measured by bone age, predicts cognitive abilities in adolescents, with more mature individuals having higher working memory and processing speed, while older teens have better verbal abilities.

The paradox of Rapid Eye Movement sleep in the light of oscillatory activity and functional synchronization during phasic and tonic microstates

This study identifies two distinct microstates within REM sleep, phasic and tonic, showing different patterns of cortical oscillations and synchronization.
