Abstract: Ensemble averaging is typically used to enhance the signal to noise ratio (SNR) of event related potentials (ERPs). This approach has the disadvantage of extending the recording time. We present an alternative approach to achieve… read more here.

DOI: 10.1073/pnas.2202116119
Abstract: Significance Consider the process of testing two vintages of wine, two TV manufacturing processes, or two recommendation algorithms to determine whether one is preferred. Under the standard model of discrete choice, we study a wide… read more here.

DOI: 10.1088/1361-6579/ac9773
Abstract: Objective. Due to the variability of human movements, muscle activations vary among trials and subjects. However, few studies investigated how data organization methods for addressing variability impact the extracted muscle synergies. Approach. Fifteen healthy subjects… read more here.

DOI: 10.1088/1741-2552/ac86f5
Abstract: Objective. Improvements in electroencephalography enable the study of the localization of active brain regions during motor tasks. Movement-related cortical potentials (MRCPs), and event-related desynchronization (ERD) and synchronization are the main motor-related cortical phenomena/neural correlates observed… read more here.
