  • Brain functional and effective connectivity based on electroencephalography recordings: a review 
    Cao, Jun; Zhao, Yifan; Shan, Xiaocai; Wei, Hua-Liang; Guo, Yuzhu; Chen, Liangyu; Erkoyuncu, John Ahmet; Sarrigiannis, Ptolemaios Georgios (Wiley, 2021-10-20)
    Functional connectivity and effective connectivity of the human brain, representing statistical dependence and directed information flow between cortical regions, significantly contribute to the study of the intrinsic brain ...
  • Dementia classification using a graph neural network on imaging of effective brain connectivity 
    Cao, Jun; Yang, Lichao; Sarrigiannis, Ptolemaios Georgios; Blackburn, Daniel; Zhao, Yifan (Elsevier, 2023-11-18)
    Alzheimer's disease (AD) and Parkinson's disease (PD) are two of the most common forms of neurodegenerative diseases. The literature suggests that effective brain connectivity (EBC) has the potential to track differences ...
  • EEG recordings as biomarkers of pain perception: where do we stand and where to go? 
    Zis, Panagiotis; Liampas, Andreas; Artemiadis, Artemios; Tsalamandris, Gabriela; Neophytou, Panagiota; Unwin, Zoe; Kimiskidis, Vasilios K.; Hadjigeorgiou, Georgios M.; Varrassi, Giustino; Zhao, Yifan; Sarrigiannis, Ptolemaios Georgios (Springer, 2022-03-23)
    Introduction: The universality and complexity of pain, which is highly prevalent, yield its significance to both patients and researchers. Developing a non-invasive tool that can objectively measure pain is of the utmost ...
  • A revised Hilbert-Huang transformation to track non-stationary association of electroencephalography signals 
    Shan, Xiaocai; Huo, Shoudong; Yang, Lichao; Cao, Jun; Zou, Jiaru; Chen, Liangyu; Sarrigiannis, Ptolemaios Georgios; Zhao, Yifan (IEEE, 2021-04-28)
    The time-varying cross-spectrum method has been used to effectively study transient and dynamic brain functional connectivity between non-stationary electroencephalography (EEG) signals. Wavelet-based cross-spectrum is one ...
  • Spatial–temporal graph convolutional network for Alzheimer classification based on brain functional connectivity imaging of electroencephalogram 
    Shan, Xiaocai; Cao, Jun; Huo, Shoudong; Chen, Liangyu; Sarrigiannis, Ptolemaios Georgios; Zhao, Yifan (Wiley, 2022-06-25)
    Functional connectivity of the human brain, representing statistical dependence of information flow between cortical regions, significantly contributes to the study of the intrinsic brain network and its functional mechanism. ...
  • Tremor after long term lithium treatment; is it cortical myoclonus? 
    Sarrigiannis, Ptolemaios Georgios; Zis, Panagiotis; Unwin, Zoe Charlotte; Blackburn, Daniel J.; Hoggard, Nigel; Zhao, Yifan; Billings, Stephen A.; Khan, Aijaz A.; Yianni, John; Hadjivassiliou, Marios (BMC (part of Springer Nature), 2019-05-22)
    Introduction: Tremor is a common side effect of treatment with lithium. Its characteristics can vary and when less rhythmical, distinction from myoclonus can be difficult. Methods: We identified 8 patients on long-term ...
