The expansion of brain-computer interfaces (BCIs) to outside the research laboratory has historically been hampered by their difficulty of use. Well-functioning BCIs often require many channels, which can be difficult to properly prepare and require expert support. Low-channel setups, however, can lead to poor or unreliable classification of intent. Here we introduce a novel method for extracting...
EEG (electroencephalography) can be analyzed quantitatively by introducing the EEG energy index in EEG preliminary examination of determination of brain death. EMD (empirical mode decomposition), MEMD (multivariate empirical mode decomposition), and 2T-EMD (turning tangent empirical mode decomposition) can be used to analyze coma and quasi-brain-death patients' EEG energy. In this paper, EMD, MEMD,...
Normal oscillations in different frequency bands have an important role in cognitive processing in the frontal region. The key issue is whether frequency oscillations of Electroencephalography (EEG) are related to cognitive task or not in occipital region. All frequency bands delta (δ), theta (θ), alpha (α), beta (β) and gamma (γ) are involved in brain tasks. This study is conducted to investigate...
A statistical analysis of the separability of EEG A-phases, with respect to basal activity, is presented in this study. A-phases are short central events that build up the Cyclic Alternating Pattern (CAP) during sleep. The CAP is a brain phenomenon which is thought to be related to the construction, destruction and instability of sleep stages dynamics. From the EEG signals, segments obtained around...
This study is mainly focused on the Electroencephalography (EEG) of alpha oscillation of normal children's handwriting behaviour and its correlation towards working memory performance. The assessment was presented to five left-handed and five right-handed children who have no records of working memory disability. The EEG signals are recorded using Neurofax-EEG 9200 (taken at channel F7, C3, F4, F8,...
Color change detection is of great importance in the study of automatic visual processing mechanisms. Although the visual mismatch negativity (vMMN) has been widely explored, the importance of induced components and the precise oscillations of EEG signal have been ignored. In the present study, we conducted the event-related (de)synchronization (ERD/ERS) of the EEG oscillatory activities relevant...
Hearing one's own name plays an important roll in external communications and internal cognition within our minds. Though hearing one's own name well has been studied, the relationship between hearing one's own name and self-awareness is not understood. In this study, we focused on brain responses to hearing one's own name. In order to assess the pattern of ERP and the power of EEG frequency during...
