Adolescence is a period of profound biopsychosocial development, with pubertally-driven neural reorganization as social demands increase in peer contexts.

Advanced aging is associated with robust changes in neural activity. In addition to the well-established age-related slowing of peak alpha frequency, there a growing body evidence showing that older age also power and beta power. Despite important progress has been made, interacting effects frequency band have not directly tested sensor source space while controlling for aperiodic components. current study we address these limitations. We recruited 54 healthy younger adults measured oscillations using high-density electroencephalogram (EEG) system during resting-state eyes closed. After preprocessing EEG data components, computed both space. Permutation two-way ANOVAs between group were performed across all electrodes dipoles. Our findings revealed significant interactions sensorimotor, parietal, occipital regions. The pattern driving interaction varied regions, progressive decrease increase from parietal sensorimotor demonstrate vary as function brain region band. interpret our context clinical preclinical on cholinergic circuit Cortico-Basal Ganglia-Thalamo-Cortical (CBGTC) circuit.

Abstract Heavy drinking during adolescence is associated to alterations in the electrophysiology of brain. However, some these are observable at pre-consumption stages. To identify brain activity profiles with alcohol consumption and address its causes, we examined power spectra functional excitation-inhibition ratio a cohort 55 adolescents within two-stage study separated by two-year follow-up. Our results indicate that power-spectra beta-band showed positive correlation use both phases (1st: rho = 0.34, p 0.042; 2nd: 0.37; 0.02) negative < 0.05; rho=-0.30; 0.01; -0.43). Finally, biological sex strong moderation effect, were females drive predictive relationship (p 0.001; 0.66; β=-0,61). Taken together, electrophysiological differences prior future prone inhibition.

The neurophysiological mechanisms supporting brain maturation are fundamental to attention and memory capacity across the lifespan. Human regions develop at different rates, with many developing into third fourth decades of life. Here, in this preregistered study (https://osf.io/gsru7), we analyzed intracranial EEG (iEEG) recordings from widespread a large developmental cohort. Using task-based (i.e., to-be-remembered visual stimuli) task-free (resting-state) data 101 children adults (5.93 - 54.00 years, 63 males;
