  1. The ten most discriminating parameters according to the Fisher (F-) coefficient and their corresponding Wilcoxon test p-values are calculated between hemispheres in the area of mesencephalon for both patients and controls.
  2. Teta, vectors of autoregressive model; AngScMom, angular second moment; SumAverg, sum average; DifEntrp, difference entropy; DiffVarnc, difference variance; WavEnLL, energy of wavelet coefficients in subband LL.
  3. * p-values of under 0.05 are considered statistically significant
