Frontoparietal Networks Mediate the Behavioral of Alpha Inhibition

Link – Frontoparietal Networks Mediate the Behavioral Impact of Alpha Inhibition in Visual Cortex. Abstract Alpha oscillations are known to play a central role in the functional inhibition of visual cortices, but the mechanisms involved are poorly understood. One noninvasive method for modulating alpha activity experimentally is through the use of flickering visual stimuli that […]

Causal links between parietal alpha activity and spatial auditory attention.

Link – Causal links between parietal alpha activity and spatial auditory attention. Abstract Both visual and auditory spatial selective attention result in lateralized alpha (8-14 Hz) oscillatory power in parietal cortex: alpha increases in the hemisphere ipsilateral to attentional focus. Brain stimulation studies suggest a causal relationship between parietal alpha and suppression of the representation […]

Inter-trial alpha power indicates mind wandering.

Link – Inter-trial alpha power indicates mind wandering. Abstract Mind wandering during ongoing tasks can impede task performance and increase the risk of failure in the laboratory as well as in daily-life tasks and work environments. Neurocognitive measures like the electroencephalography (EEG) offer the opportunity to assess mind wandering non-invasively without interfering with the primary […]

tDCS and EEG study on attention and vigilance

Link – A High-Definition tDCS and EEG study on attention and vigilance: Brain stimulation mitigates the executive but not the arousal vigilance decrement. Abstract Attention comprises a wide set of processes such as phasic alertness, orienting, executive control, and the executive (i.e., detecting infrequent targets) and arousal (i.e., sustaining a fast reaction) vigilance components. Importantly, […]

Mathematical mechanism of alpha rhythm in the human brain.

Link – Mathematical mechanism of state-dependent phase resetting properties of alpha rhythm in the human brain. Abstract It is well-known that 10-Hz alpha oscillations in humans observed by electroencephalogram (EEG) are enhanced when the eyes are closed. Toward explaining this, a previous experimental study using manipulation by transcranial magnetic stimulation (TMS) revealed more global propagation […]

Anodal occipital tDCS enhances spontaneous alpha activity.

Link – Anodal occipital tDCS enhances spontaneous alpha activity. Neurosci Lett. 2020 Jan 29;:134796 Authors: Dong G, Wang Y, Chen X Abstract Transcranial direct current stimulation (tDCS) is a form of brain stimulation technique that modulates neuronal excitability changes in targeted cerebral areas through a constant low current. The existing studies mainly concentrated in tDCS […]

Differences in neural spectral power during motor learning

Link – Age-related differences in neural spectral power during motor learning. Neurobiol Aging. 2019 Jan 06;77:44-57 Authors: Rueda-Delgado LM, Heise KF, Daffertshofer A, Mantini D, Swinnen SP Abstract We investigated how older adults preserve the capability to acquire new motor skills in the face of age-related brain alterations. We assessed neural changes associated with learning […]

Stimulus-driven brain rhythms within the alpha band

Link – Stimulus-driven brain rhythms within the alpha band: The attentional-modulation conundrum. J Neurosci. 2019 Feb 15;: Authors: Keitel C, Keitel A, Benwell CS, Daube C, Thut G, Gross J Abstract Two largely independent research lines use rhythmic sensory stimulation to study visual processing. Despite the use of strikingly similar experimental paradigms, they differ crucially […]

Individual EEG alpha profiles are gender-dependent

Link – Individual EEG alpha profiles are gender-dependent and indicate subjective experiences in whole-body perceptual deprivation. Neuropsychologia. 2019 Jan 31;: Authors: Glicksohn J, Berkovich-Ohana A, Mauro F, Ben-Soussan TD Abstract We use a unique environment of Whole Body Perceptual Deprivation (WBPD) to induce an altered state of consciousness (ASC) in our participants, and employ online […]
