A model of variability in brain stimulation evoked responses.
(Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Conference, 2012)The input-output (IO) curve of cortical neuron populations is a key measure of neural excitability and is related to other response measures including the motor threshold which is widely used for individualization ... -
A Modular Multilevel Series/Parallel Converter for a Wide Frequency Range Operation
(IEEE Transactions on Power Electronics, 2019-10-01)When providing ac output, modular multilevel converters (MMCs) experience power fluctuation in the phase arms. The power fluctuation causes voltage ripple on the module capacitors, which grows with the output power and inversely ... -
A Reduced Series/Parallel Module for Cascade Multilevel Static Compensators Supporting Sensorless Balancing
(IEEE Transactions on Industrial Electronics, 2020) -
Complementary topology of maintenance and manipulation brain networks in working memory.
(Scientific reports, 2018-12-13)Working memory (WM) is assumed to consist of a process that sustains memory representations in an active state (maintenance) and a process that operates on these activated representations (manipulation). We examined evidence ... -
Modular Multilevel Series/Parallel Converter for Bipolar DC Distribution and Transmission
(IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020) -
Modulation and Control of Series/Parallel Module for Ripple-Current Reduction in Star-Configured Split-Battery Applications
(IEEE Transactions on Power Electronics, 2020) -
Noninvasive Detection of Motor-Evoked Potentials in Response to Brain Stimulation Below the Noise Floor-How Weak Can a Stimulus Be and Still Stimulate.
(Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference, 2018-07)Motor-evoked potentials (MEP) are one of the most important responses to brain stimulation, such as supra-threshold transcranial magnetic stimulation (TMS) and electrical stimulation. The understanding of the neurophysiology ... -
Older adults benefit from more widespread brain network integration during working memory.
(NeuroImage, 2020-05-19)Neuroimaging evidence suggests that the aging brain relies on a more distributed set of cortical regions than younger adults in order to maintain successful levels of performance during demanding cognitive tasks. However, ... -
Online repetitive transcranial magnetic stimulation during working memory in younger and older adults: A randomized within-subject comparison.
(PloS one, 2019-01)Working memory is the ability to perform mental operations on information that is stored in a flexible, limited capacity buffer. The ability to manipulate information in working memory is central to many aspects of human ...
