Development of Brainwave Balancing Index Using EEG

Alpha and beta EEG brainwave signal classification technique: A conceptual study

“…Artifact from subject such as body movement, EMG or ECG can be reduces by conducting proper EEG procedure. But artifact from technical such as 50-60 Hz power line noise can only be removed by filtering [8] [15].…”

“…Notch filter was use to remove the 50 Hz power line noise [8] [15].In addition, software such as Savitzky-Golay [2], Matlab algorithm [7][8], Independent Component Analysis, ICA [14] [16] can be used to remove the artifact in brainwave signal. Furthermore, the metric in the filter data can be calculated in each of the electrode.…”

“…Power specral density, PSD is the most common feature use in the analysis data of EEG [7][8][9][10] [24]. PSD can be obtain from the extraction using welch or hanning window and Fast Fouries Transformer, FFT [3] [9].…”

“…The total number of subject for this research is 20 people, consist of 10 subjects of healthy person and 10 subjects of stroke patient. The healthy person is act as control subject for the comparison data, aged between 18 to 50 years old, medically fit, and no history of any neurological disease, seizures or psychiatric disorder [2][5] [8]. For the stroke patient, they are the subject that suffer from stroke and admitted to a rehabilitation centre [1].The stroke patient is the post-stroke for 3-15 month, paralyzed on lower part of the body and able to perform the FES-assisted exercised and EEG procedure [1][2].…”

Neuro-Feedback System Enhancing the Level of Symmetry in Left and Right Brain Activities

“…Pandriad et al assessed the impact of biofeedback and neurofeedback training on smokers working on smoking cessation projects, exploring possible correlations between subjective mood scores and training performance [16]. Murat et al developed the brainwave balancing index (BBI), which uses the subject's ability to think and work as direct indicators to generate vast opportunities for improving human potential [17]. Cevat Unal et al suggested that gamma activity was significantly higher on the right side of the brain compared to the left side [18], and Sümeyra Altan et al suggested that neurofeedback can be used to restore sympathovagal imbalances.…”
