Eeg representation
WebII.B. Topographic EEG displays can present visually a spatial representation of raw EEG data (i.e., voltage amplitude) or a derived parameter (e.g., power in a given frequency band, or peak latency). Typically, the parameter under study is mapped onto a stylized picture of the head or the brain, but may be mapped onto an WebThis paper presents a deep learning driven electroencephalography (EEG) -BCI system to perform decoding of hand motor imagery using deep convolution neural network architecture, with spectrally localized time-domain representation of …
