Phenotypic and movement-dependent periodic and aperiodic activity in Parkinson's STN-LFP recordings.
OBJECTIVE Traditional analyses of subthalamic nucleus local field potentials (STN-LFPs) may obscure relevant dynamics by conflating periodic and aperiodic activity. We investigated whether spectral parameterization reveals phenotype- and movement-dependent neural signatures in Parkinson's disease (PD). METHODS Intrao...
