Functional Connectivity Analysis of Mental Fatigue Reveals Different Network Topological Alterations Between Driving and Vigilance Tasks
Georgios N. Dimitrakopoulos,Ioannis Kakkos,Zhongxiang Dai,Hongtao Wang,Kyriakos N. Sgarbas,Nitish V. Thakor,Anastasios Bezerianos,Yu Sun +7 more
TL;DR: The topological alterations of functional brain networks in the theta band of electroencephalography data from 40 male subjects undergoing two distinct fatigue-inducing tasks are investigated to demonstrate the feasibility of using functional connectivity as neural biomarkers for applicable fatigue monitoring.
Journal ArticleDOI
Task-Independent Mental Workload Classification Based Upon Common Multiband EEG Cortical Connectivity
Georgios N. Dimitrakopoulos,Ioannis Kakkos,Zhongxiang Dai,Julian Lim,Joshua deSouza,Anastasios Bezerianos,Yu Sun +6 more
TL;DR: A framework for cross- as well as within-task workload discrimination by utilizing multiband electroencephalography (EEG) cortical brain connectivity is presented and a small number of discriminative interactions among brain areas are detected, leading to high accuracy in both within- task and cross-task classifications.
Journal ArticleDOI
Mental Workload Drives Different Reorganizations of Functional Cortical Connectivity Between 2D and 3D Simulated Flight Experiments
Ioannis Kakkos,Georgios N. Dimitrakopoulos,Lingyun Gao,Yuan Zhang,Peng Qi,George K. Matsopoulos,Nitish V. Thakor,Anastasios Bezerianos,Yu Sun +8 more
TL;DR: It is found that increased alpha band efficiencies and beta band local efficiency were associated with elevated mental workload levels, while beta band global efficiency exhibited distinct development trends between 2D and 3D interfaces.
Journal ArticleDOI
EEG Fingerprints of Task-Independent Mental Workload Discrimination
Ioannis Kakkos,Georgios N. Dimitrakopoulos,Yi Sun,Jingjia Yuan,George K. Matsopoulos,Anastasios Bezerianos,Yu Sun +6 more
TL;DR: In this article, a data-driven analysis framework was introduced to overcome the challenges regarding task-independent workload assessment using a fusion of EEG spectral characteristics and unveil the common neural mechanisms underlying mental workload.
Journal ArticleDOI
Neuroprotective assessment of prolonged local hypothermia post contusive spinal cord injury in rodent model
Daniel Boon Loong Teh,Soo Min Chua,Ankshita Prasad,Ioannis Kakkos,Wenxuan Jiang,Mu Yue,Xiaogang Liu,Angelo H. All,Angelo H. All +8 more
TL;DR: Early local moderate hypothermia can be induced for extended periods of time post SCI in the rodent model and improves functional electrophysiological outcome and motor behavior recovery for a long time, lasting until 8 weeks.
