    Integrative brain states facilitate the expression of Parkinson’s tremor

    MF. Dirkx, M. Shine, RC. Helmich (Nijmegen, Netherlands)

    Objective: To test the hypothesis that fluctuations in integrative brain states and/or arousal drive spontaneous fluctuations in PD rest tremor. Background: Parkinson’s disease (PD) rest…

    Machine learning selects common fMRI features of cognitive impairment in Parkinson’s disease from cross-institution datasets

    CY. Chien, TY. Lin, TL. Lee, CCK. Lin (Tainan, Taiwan)

    Objective: To obtain common features of Parkinson's disease (PD) with cognitive impairment (CI) in resting-state functional MRI (rs-fMRI) from cross-institution datasets by adopting machine learning.…
