We propose event-related cortical sources estimation from subject-independent electroencephalogram (EEG) recordings for motor imagery brain computer interface (BCI). By using wavelet-based maximum entropy on the mean (wMEM), task-specific EEG channels are selected to predict right hand and right foot sensorimotor tasks, employing spatial pattern analysis with and without covariance estimation regularization. EEG from five healthy […]

Understanding how neurons arrange themselves into neural networks that result in behaviors is a major goal in neuroscience. Most theoretical and experimental efforts have focused on a top-down approach which seeks to identify neuronal correlates of behaviors. This has been accomplished by effectively mapping specific behaviors to distinct neural patterns or by creating computational models […]

Although the neural mechanism supporting episodic recollection has been well characterized in younger adults, exactly how recollection is supported in older adults remains unclear. The electrophysiological correlate of recollection – the parietal retrieval success effect – for example, has been shown to be sensitive to both the amount of information recollected and the accuracy of […]
