This study describes the picture of cortical connections when bilinguals switch between their first and second language. Event-related potentials (ERPs) were measured in 21 Chinese-English bilinguals during the monolingual task selection context (TSc) and bilingual language selection context (LSc) picture-naming tasks. Then, the wavelet transforms of ERP records were used, and the regions of interest...
Combining non-invasive monitoring of action-related brain signals with the invasive recordings of the nerve motor output could provide robust natural and bidirectional multimodal Brain-Machine interfaces. One 26 years old, right-handed male who had suffered traumatic trans-radial amputation of the left arm was connected in a bidirectional way with a robotic hand prostheses. Cortical signals related...
This work aims to analyze the reference (montage) problem in electroencephalographic (EEG) recordings. It is well accepted that EEG signals are a mixture of cerebral and extracerebral sources, and the solution to the reference problem depends on the hypothesized mixing model. We focus here on an acquisition model using a distant reference electrode and propose a method for determining and eliminating...
