Correlation of EEG Band Power and Hand Motion Trajectory
نویسندگان
چکیده
A preliminary analysis of the correlation between high resolution EEG and three dimensional (3D) hand motion trajectories is presented. The study involved assessing which EEG frequency components and cortical areas show the most significant correlation with hand motion trajectory towards five targets positioned in different locations in space. The time shift between time-power pattern of the selected EEG frequency and related motion trajectory is also analyzed. The results show strong correlation between EEG and kinetic data in low frequency (0.5-4Hz) range as well as significant correlations in the 28-36Hz range. The results indicate that these EEG frequency bands may best be used to develop an EEG-based brain-computer interface (BCI) for the decoding of 3D hand motion trajectories.

Time varying EEG Bandpower Estimation Improves 3D Hand Motion Trajectory Prediction Accuracy
Introduction: Motion trajectory prediction (MTP) employs a time-series of band-pass filtered EEG potentials for reconstructing the three dimensional (3D) trajectory of limb movements with a multiple linear regression (mLR) block. While traditional multiclass classification methods use power values of mu (8-12Hz) and beta (12-30Hz) bands for limb movement based classification, recent MTP brain-c...
متن کاملEEG Mu and Beta Bandpower Encodes Information for 3D Hand Motion Trajectory Prediction
A motion trajectory prediction (MTP) based brain-computer interface (BCI) aims to reconstruct the three-dimensional (3D) trajectory of upper limb movement using electroencephalography (EEG). The most common MTP BCI employs a time-series of band-pass filtered EEG potential (referred to here as the potential time-series (PTS) model) for reconstructing the trajectory of a 3D limb movement using mu...

Objective: To date, motion trajectory prediction (MTP) of a limb from non-invasive electroencephalography (EEG) has relied, primarily, on band-pass filtered samples of EEG potentials i.e., the potential time-series model. Most MTP studies involve decoding 2D and 3D arm movements i.e., executed arm movements. Decoding of observed or imagined 3D movements has been demonstrated with limited succes...

The aim of this study was to clarify the relationship between EEG power and neuroticism trait. We used correlational method in order to examine the hypotheses. The participants included twenty-five undergraduate students (age mean= 21.36, SD= 23.39) at Ferdowsi university of Mashhad that were selected as volunteers. All participants were right-handed and had normal or corrected-to-normal visual...
متن کاملAdaptive estimation of hand movement trajectory in an EEG based brain-computer interface system.
OBJECTIVE The various parameters that define a hand movement such as its trajectory, speed, etc, are encoded in distinct brain activities. Decoding this information from neurophysiological recordings is a less explored area of brain-computer interface (BCI) research. Applying non-invasive recordings such as electroencephalography (EEG) for decoding makes the problem more challenging, as the enc...
