Vigilance declines following sleep deprivation are associated with two previously identified dynamic connectivity states

Publication date: Available online 2 July 2019Source: NeuroImageAuthor(s): James Teng, Ju Lynn Ong, Amiya Patanaik, Jesisca Tandi, Juan Helen Zhou, Michael W.L. Chee, Julian LimAbstractRobustly linking dynamic functional connectivity (DFC) states to behaviour is important for establishing the utility of the method as a functional measurement. We previously used a sliding window approach to identify two dynamic connectivity states (DCS) related to vigilance. A new sample of 32 healthy participants...

ICA-based denoising for ASL perfusion imaging

Publication date: Available online 2 July 2019Source: NeuroImageAuthor(s): D. Carone, G.W.J. Harston, J. Garrard, F. De Angeli, L. Griffanti, T.W. Okell, M.A. Chappell, J. KennedyAbstractArterial Spin Labelling (ASL) imaging derives a perfusion image by tracing the accumulation of magnetically labeled blood water in the brain. As the image generated has an intrinsically low signal to noise ratio (SNR), multiple measurements are routinely acquired and averaged, at a penalty of increased scan duration...
