NPJ Parkinsons Dis. 2022 Nov 23;8(1):161. doi: 10.1038/s41531-022-00420-w.ABSTRACTWhilst involvement of the motor cortex in the phenomenon of freezing in Parkinson's disease has been previously suggested, few empiric studies have been conducted to date. We investigated motor cortex (M1) excitability in eleven right-handed Parkinson's disease patients (aged 69.7 ± 9.6 years, disease duration 11.2 ± 3.9 years, akinesia-rigidity type) with verified ... read more
