Co-Increasing Neuronal Noise and Beta Power in the Developing Brain [article]

Wei He, Thomas Donoghue, Paul F Sowman, Robert A Seymour, Jon Brock, Stephen Crain, Bradley Voytek, Arjan Hillebrand
2019 bioRxiv   pre-print
Beamformer-reconstructed MEG time-series allowed a direct comparison of power in the source domain between 24 children (8.0 ± 2.5 years, 17 males) and 24 adults (40.6 ± 17.4 years, 16 males).  ...  When estimating both the periodic and aperiodic components, we found that power increases with age in the beta band only, and that the 1/f signal is flattened in adults compared to children.  ...  5 63 (Berchicci et al., 2011) and age-related increases in beta power between age 9-14 and 20-42 64 Outstanding Questions 79 Spectral analysis of resting-state MEG/EEG recordings has proven to be a  ...

Development of face recognition: Dynamic causal modelling of MEG data

Wei He, Blake W. Johnson
2018 Developmental Cognitive Neuroscience  
Electrophysiological studies of adults indicate that brain activity is enhanced during viewing of repeated faces, at a latency of about 250 ms after the onset of the face (M250/N250).  ...  The present study aimed to determine if this effect was also present in preschool-aged children, whose brain activity was measured in a custom-sized pediatric MEG system.  ...  Acknowledgements This work was supported by the Australian Research Council Centre of Excellence for Cognition and its Disorders (grant number CE110001021), http://www.ccd.edu.au.  ...

We provide an overview of these methods in a systematic manner, organized by their domain of application including functional connectivity, anatomical structure, and electrical-based analysis.  ...  A major limitation of existing methods has been the focus on grid-like data; however, the structure of physiological recordings are often irregular and unordered, which makes it difficult to conceptualise  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...
