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 […]
