A new algorithm based on hidden Markov models (HMM) to discriminate single trial electroencephalogram (EEG) between two conditions of finger movement task is proposed. Firstly, multi-channel EEG signals of single trial are filtered in both frequency and spatial domains. The pass bands of the two filters in frequency domain are 0~3 Hz and 8~30 Hz respectively, and the spatial filters are designed by...
Under conditions in which the visual system can not reconcile dissimilar images from the two eyes, perception typically alternates between the two images - a process known as binocular rivalry. Binocular rivalry is a useful experimental paradigm for identifying aspects of neural correlates. Two images flickered at different frequencies as the visual stimulator to left and right eyes respectively so...
Detection of the seizure vulnerable period (SVP) is significant for epilepsy patients. Based on the construction of epilepsy rat model, we observed that SVP existed by long-term EEG recordings of a rat. Further analysis of the recordings by Lempel-Ziv complexity measure, we found that the complexities during the seizure vulnerable period were significantly lower than those during the seizure free...
