Aberrant Whole-Brain Transitions and Dynamics of Spontaneous Network Microstates in Mild Traumatic Brain Injury

Frontiers in Computational Neuroscience, 2020
Dynamic Functional Connectivity (DFC) analysis is a promising approach for the characterization of brain electrophysiological activity. In this study, we investigated abnormal alterations due to mild Traumatic Brain Injury (mTBI) using DFC of the source ...

Reducing feedback requirements of the multiple weight opportunistic beamforming scheme via selective multiuser diversity [PDF]

, 2008
Opportunistic beamforming (OB) relies on the transmission of Channel State Information (CSI) in the form of instantaneous Signal to Noise Ratio (SNR) from Mobile Stations (MSs) back to the Base Station (BS) for scheduling purposes that increase ...

Reorganization of functional and directed corticomuscular connectivity during precision grip from childhood to adulthood

Scientific Reports, 2021
How does the neural control of fine movements develop from childhood to adulthood? Here, we investigated developmental differences in functional corticomuscular connectivity using coherence analyses in 111 individuals from four different age groups ...

On the effect of SNR and superdirective beamforming in speaker diarisation in meetings [PDF]

, 2012
This paper examines the effect of sensor performance on speaker diarisation in meetings and investigates the use of more advanced beamforming techniques, beyond the typically employed delay-sum beamformer, for mitigating the effects of poorer sensor ...

Beamforming of ictal MEG aiding subtle focal cortical dysplasia localization

Epilepsy & Behavior Reports
A case is presented of a 17-year-old right-handed male with drug-resistant epilepsy (DRE), initially presenting with non-lesional MRI findings, where ictal MEG beamforming successfully localized a subtle Focal Cortical Dysplasia (FCD).

Localization of the Epileptogenic Zone Using Interictal MEG and Machine Learning in a Large Cohort of Drug-Resistant Epilepsy Patients

Frontiers in Neurology, 2018
Objective: Epilepsy surgery results in seizure freedom in the majority of drug-resistant patients. To improve surgery outcome we studied whether MEG metrics combined with machine learning can improve localization of the epileptogenic zone, thereby ...
