Reconfiguration of directed functional connectivity among neurocognitive networks with aging: Considering the role of thalamo-cortical interactions

M Das, V Singh, LQ Uddin, A Banerjee, D Roy - Cerebral Cortex, 2021 - academic.oup.com
A complete picture of how subcortical nodes, such as the thalamus, exert directional influence
on large-scale brain network interactions across age remains elusive. Using directed …

[HTML][HTML] The role of alpha-rhythm states in perceptual learning: insights from experiments and computational models

R Sigala, S Haufe, D Roy, HR Dinse… - Frontiers in computational …, 2014 - frontiersin.org
During the past two decades growing evidence indicates that brain oscillations in the alpha
band (~10 Hz) not only reflect an “idle” state of cortical activity, but also take a more active …

[HTML][HTML] Atypical flexibility in dynamic functional connectivity quantifies the severity in autism spectrum disorder

V Harlalka, RS Bapi, PK Vinod, D Roy - Frontiers in human …, 2019 - frontiersin.org
Resting-state functional connectivity (FC) analyses have shown atypical connectivity in
autism spectrum disorder (ASD) as compared to typically developing (TD). However, this view …

Aperiodic and periodic components of ongoing oscillatory brain dynamics link distinct functional aspects of cognition across adult lifespan

K Thuwal, A Banerjee, D Roy - Eneuro, 2021 - eneuro.org
Signal transmission in the brain propagates via distinct oscillatory frequency bands but the
aperiodic component, 1/f activity, almost always co-exists which most of the previous studies …

Metastability in senescence

S Naik, A Banerjee, RS Bapi, G Deco, D Roy - Trends in cognitive sciences, 2017 - cell.com
The brain during healthy aging exhibits gradual deterioration of structure but maintains a
high level of cognitive ability. These structural changes are often accompanied by …
