Relaxed mental state detection using the Emotiv Epoc and Adaptive Threshold Algorithms
… over the occipital brain region and monitoring alpha wave activity. Said activity is characterized using an adaptive subject-specific threshold algorithm. Different variations of the threshold algorithm were investigated and their performance was compared using receiver operating characteristic …

Effect of Prior Trauma Exposure on Alpha Amplitude, Heart Rate, and Self-Reported Negative Affect
… intervention or the inert control intervention. Alpha wave amplitude, as measured by EEG, and heart rate were assessed at three different times throughout the protocol. Participants’ self-reported negative affect was also measured at those same three times using the Positive and Negative Affect …

THE EFFECTIVENESS OF BUPROPION SR ON DEPRESSIVE SYMPTOMS IN SMOKERS: SELF-REPORTS, EEG, AND INDIVIDUAL DIFFERENCES
… Glassman et al., 1998). Here the parietal EEG alpha asymmetry was used as a dimensional neuropsychological marker of depressive symptoms (i.e., the more depressed, the higher alpha power in the right vs. left parietal lobe during visuospatial tasks [Henriques & Davidson, 1997; Rabe et al, …

Employing Intracranial EEG Data to Decipher Sleep Neural Dynamics
… different stages that involve changes in brainwave patterns. Intracranial EEG (iEEG) is an invasive brain recording technique used in hospital settings in epileptic patients to determine the focus of their seizure activity. The intracranial data recorded allows one to directly observe the …

A microanalysis of EMG and EEG changes during the sleep onset period (SOP) : a theoretical investigation with practical applications /
… been generally defined with regards to brain wave activity (Recht schaff en & Kales (1968); and more precisely by Hori, Hayashi, & Morikawa (1994)). However, no previous study has attempted to quantify the changes in muscle activity during this same process. The practical aspect of the study …
