Task-based dynamic functional connectivity: Recent findings and open questions

J Gonzalez-Castillo, PA Bandettini - Neuroimage, 2018 - Elsevier
The temporal evolution of functional connectivity (FC) within the confines of individual scans
is nowadays often explored with functional neuroimaging. This is particularly true for resting …

Spontaneous brain oscillations and perceptual decision-making

J Samaha, L Iemi, S Haegens, NA Busch - Trends in cognitive sciences, 2020 - cell.com
Making rapid decisions on the basis of sensory information is essential to everyday
behaviors. Why, then, are perceptual decisions so variable despite unchanging inputs …

Spontaneous neural oscillations bias perception by modulating baseline excitability

L Iemi, M Chaumon, SM Crouzet… - Journal of …, 2017 - Soc Neuroscience
The brain exhibits organized fluctuations of neural activity, even in the absence of tasks or
sensory input. A prominent type of such spontaneous activity is the alpha rhythm, which …

Language prediction is reflected by coupling between frontal gamma and posterior alpha oscillations

L Wang, P Hagoort, O Jensen - Journal of cognitive neuroscience, 2018 - direct.mit.edu
Readers and listeners actively predict upcoming words during language processing. These
predictions might serve to support the unification of incoming words into sentence context …

Spatial attentional selection modulates early visual stimulus processing independently of visual alpha modulations

C Gundlach, S Moratti, N Forschack… - Cerebral Cortex, 2020 - academic.oup.com
The capacity-limited human brain is constantly confronted with a huge amount of sensory
information. Selective attention is needed for biasing neural processing towards relevant …

Decoding object-based auditory attention from source-reconstructed MEG alpha oscillations

IEJ de Vries, G Marinato, D Baldauf - Journal of Neuroscience, 2021 - Soc Neuroscience
How do we attend to relevant auditory information in complex naturalistic scenes? Much
research has focused on detecting which information is attended, without regarding …

Moment-to-moment fluctuations in neuronal excitability bias subjective perception rather than strategic decision-making

L Iemi, NA Busch - Eneuro, 2018 - eneuro.org
Perceiving an external stimulus depends not only on the physical features of the stimulus,
but also fundamentally on the current state of neuronal excitability, indexed by the power of …

Oscillatory mechanisms of stimulus processing and selection in the visual and auditory systems: state-of-the-art, speculations and suggestions

B Zoefel, R VanRullen - Frontiers in Neuroscience, 2017 - frontiersin.org
All sensory systems need to continuously prioritize and select incoming stimuli in order to
avoid overflow or interference, and provide a structure to the brain's input. However, the …

Imaging the spontaneous flow of thought: Distinct periods of cognition contribute to dynamic functional connectivity during rest

J Gonzalez-Castillo, C Caballero-Gaudes, N Topolski… - NeuroImage, 2019 - Elsevier
Brain functional connectivity (FC) changes have been measured across seconds using fMRI.
This is true for both rest and task scenarios. Moreover, it is well accepted that task …

Auditory sensitivity and decision criteria oscillate at different frequencies separately for the two ears

HT Ho, J Leung, DC Burr, D Alais, MC Morrone - Current Biology, 2017 - cell.com
Many behavioral measures of visual perception fluctuate continually in a rhythmic manner,
reflecting the influence of endogenous brain oscillations, particularly theta (∼ 4–7 Hz) and …
