Hearing and seeing meaning in noise: Alpha, beta and gamma oscillations predict gestural enhancement of degraded speech comprehension
degraded speech gesture magnetoencephalography multimodal integration oscillations, semantics
2018/3/5
During face-to-face communication, listeners integrate speech with gestures. The semantic information conveyed by iconic gestures (e.g., a drinking gesture) can aid speech comprehension in adverse lis...
Prestimulus Alpha Oscillations and the Temporal Sequencing of Audio-visual Events
Prestimulus Alpha Oscillations Audio-visual Events
2017/8/29
Perceiving the temporal order of sensory events typically depends on participants' attentional state, thus likely on the endogenous fluctuations of brain activity. Using magnetoencephalography, we sou...
Alpha-Beta and Gamma Rhythms Subserve Feedback and Feedforward Influences among Human Visual Cortical Areas
Alpha-Beta Gamma Rhythms Subserve Feedback Feedforward Influences Human Visual Cortical Areas
2016/5/3
Primate visual cortex is hierarchically organized. Bottom-up and top-down influences are exerted through distinct frequency channels, as was recently revealed in macaques by correlating inter-areal in...
Alpha and gamma band oscillations index differential processing of acoustically reduced and full forms
Cognitive load Neuronal oscillations Semantic integration Speech comprehension Speech reduction
2016/5/3
Reduced forms like yeshay for yesterday often occur in conversations. Previous behavioral research reported a processing advantage for full over reduced forms. The present study investigated whether t...
Directed Communication between Nucleus Accumbens and Neocortex in Humans Is Differentially Supported by Synchronization in the Theta and Alpha Band
Nucleus Accumbens Neocortex
2015/12/18
Here, we report evidence for oscillatory bi-directional interactions between the nucleus
accumbens and the neocortex in humans. Six patients performed a demanding covert
visual attention task while ...
Occipital Alpha Activity during Stimulus Processing Gates the Information Flow to Object-Selective Cortex
Occipital Alpha Stimulus Processing Gates Information Flow Object-Selective Cortex
2015/5/6
Given the limited processing capabilities of the sensory system, it is essential that attended information is gated to downstream areas, whereas unattended information is blocked. While it has been pr...
Word class and context affect alpha-band oscillatory dynamics in an older population
lexical-semantic reading EEG oscillatory dynamics alpha theta
2015/4/21
Differences in the oscillatory EEG dynamics of reading open class (OC) and closed class (CC) words have previously been found (Bastiaansen et al., 2005) and are thought to reflect differences in lexic...

Any two Z-related set-classes will map onto one another under 1) TnM or TnMI, or 2) TnM or TnMI in tandem with Morris’s alpha operations, or 3) maximally alpha-like operations, the original contributi...
