Improved detection of Parkinsonian resting tremor with feature engineering and Kalman filtering.
Clinical neurophysiology : official journal of the International Federation of Clinical Neurophysiology
Nov 5, 2019
OBJECTIVE: Accurate and reliable detection of tremor onset in Parkinson's disease (PD) is critical to the success of adaptive deep brain stimulation (aDBS) therapy. Here, we investigated the potential use of feature engineering and machine learning m...
Feedback delays can enhance anticipatory synchronization in human-machine interaction.
PloS one
Aug 22, 2019
Research investigating the dynamics of coupled physical systems has demonstrated that small feedback delays can allow a dynamic response system to anticipate chaotic behavior. This counterintuitive phenomenon, termed anticipatory synchronization, has...
Models of the effect of teleoperation transmission delay on robot movement time.
Ergonomics
Jul 8, 2019
Recent research of [Scholcover and Gillan ( 2018 )] has shown experimentally that system transmission delay has a linear effect on the time taken to perform a complex tracking task with a simple teleoperated robot. This note shows that, for the case ...
Tutorial and simulations with ADAM: an adaptation and anticipation model of sensorimotor synchronization.
Biological cybernetics
Apr 8, 2019
Interpersonal coordination of movements often involves precise synchronization of action timing, particularly in expert domains such as ensemble music performance. According to the adaptation and anticipation model (ADAM) of sensorimotor synchronizat...
Cyborg groups enhance face recognition in crowded environments.
PloS one
Mar 6, 2019
Recognizing a person in a crowded environment is a challenging, yet critical, visual-search task for both humans and machine-vision algorithms. This paper explores the possibility of combining a residual neural network (ResNet), brain-computer interf...
Extracellular GABA assisting in organizing dynamic cell assemblies to shorten reaction time to sensory stimulation.
Biological cybernetics
Feb 12, 2019
Until recently, glia, which exceeds the number of neurons, was considered to only have supportive roles in the central nervous system, providing homeostatic controls and metabolic supports. However, recent studies suggest that glia interacts with neu...
The onset and post-onset auditory responses of cochlear nucleus neurons are modulated differently by cortical activation.
Hearing research
Dec 31, 2018
Auditory cortex exhibit a capacity of modulating the functions of subcortical auditory nuclei and even inner ear through descending pathways. The cochlear nucleus (CN), which acts as the gateway from the auditory periphery to the central auditory sys...
Sensorimotor Robotic Measures of tDCS- and HD-tDCS-Enhanced Motor Learning in Children.
Neural plasticity
Dec 18, 2018
Transcranial direct-current stimulation (tDCS) enhances motor learning in adults. We have demonstrated that anodal tDCS and high-definition (HD) tDCS of the motor cortex can enhance motor skill acquisition in children, but behavioral mechanisms remai...
Perceptual Decision-Making: Biases in Post-Error Reaction Times Explained by Attractor Network Dynamics.
The Journal of neuroscience : the official journal of the Society for Neuroscience
Nov 30, 2018
Perceptual decision-making is the subject of many experimental and theoretical studies. Most modeling analyses are based on statistical processes of accumulation of evidence. In contrast, very few works confront attractor network models' predictions ...
Machine learning provides novel neurophysiological features that predict performance to inhibit automated responses.
Scientific reports
Nov 2, 2018
Neurophysiological features like event-related potentials (ERPs) have long been used to identify different cognitive sub-processes that may contribute to task performance. It has however remained unclear whether "classical" ERPs are truly the best re...
