The generation and propagation of the human alpha rhythm [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2019 Abstract The alpha rhythm is the longest studied brain oscillation and has been theorized to play a key role in cognition. Still, its physiology is poorly understood. In this study, we used micro and macro electrodes in surgical epilepsy patients to measure the intracortical and thalamic generators of the alpha rhythm during quiet ...

Genetic association of apolipoprotein E genotype with EEG alpha rhythm slowing and functional brain network alterations during normal aging [PDF]
Frontiers in Neuroscience, 2022 The ε4 allele of the apolipoprotein E (APOE4+) genotype is a major genetic risk factor for Alzheimer’s disease (AD), but the mechanisms underlying its influence remain incompletely understood.

Alpha rhythm of electroencephalography was modulated differently by three transcranial direct current stimulation protocols in patients with ischemic stroke [PDF]
Frontiers in Human Neuroscience, 2022 The heterogeneity of transcranial direct current stimulation (tDCS) protocols and clinical profiles may explain variable results in modulating excitability in the motor cortex after stroke.

The alpha rhythm: from physiology to behavior. [PDF]
Physiol RevThe alpha rhythm, first identified by Hans Berger 100 years ago, is the dominant noninvasive electrophysiological signature of the healthy human brain in the awake state. For decades, it was believed that the alpha rhythm reflected rest or idling; however, this perspective changed in the 2000s when researchers found that alpha oscillations increase ...

Modulation of Somatosensory Alpha Rhythm by Transcranial Alternating Current Stimulation at Mu-Frequency [PDF]
Frontiers in Human Neuroscience, 2017 Introduction: Transcranial alternating current stimulation (tACS) is emerging as an interventional tool to modulate different functions of the brain, potentially by interacting with intrinsic ongoing neuronal oscillations.

Abnormal Alpha Rhythm During Self-Referential Processing in Schizophrenia Patients [PDF]
Frontiers in Psychiatry, 2019 Schizophrenia patients exhibited a psychological abnormal appearance when they recognized objects related to themselves. This cognitive process is associated with self-referential processing.
