Journal ArticleDOI
Atypical Flexibility in Dynamic Functional Connectivity Quantifies the Severity in Autism Spectrum Disorder.
TL;DR: A strong positive correlation of symptom severity with flexibility of rigid areas and with disjointness of sensorimotor areas is found in ASD, demonstrating that the dynamic framework best characterizes the variability in ASD.
Journal ArticleDOI
The role of alpha-rhythm states in perceptual learning: insights from experiments and computational models.
TL;DR: In this paper, the authors disentangle the alpha rhythm into different neural signatures that control information processing within individual functional building blocks of perceptual learning and further highlight computational studies that shed light on potential mechanisms regarding how alpha oscillations may modulate information transfer and connectivity changes relevant for learning.
Journal ArticleDOI
Metastability in Senescence
TL;DR: It is hypothesized that the continuous process of aging can be explained by the concepts of metastability - a theoretical framework that gives a systematic account of the variability of the brain.
Journal ArticleDOI
Using the Virtual Brain to Reveal the Role of Oscillations and Plasticity in Shaping Brain's Dynamical Landscape

TL;DR: This work demonstrates the capability of spike-timing-dependent plasticity (STDP) combined with intrinsic alpha (8-12 Hz) oscillations to efficiently influence learning and shows how alpha-state-dependent STDP alters the local area dynamics from an irregular to a highly periodic alpha-like state.
Journal ArticleDOI
Integrative Analysis of Hippocampus Gene Expression Profiles Identifies Network Alterations in Aging and Alzheimer's Disease.
TL;DR: The hippocampus is vulnerable to damage at early stages of AD and altered neurogenesis in the hippocampus is linked to the onset of AD, so simultaneously analyzing aging and AD will help to understand the pre-clinical and clinical phase of AD
