### Global Wavelet Profiles of Control and Parkinson's Disease Men under 60 Years Old (\(<\)60)  
Figure 2 shows the global wavelet profiles of the CL and PD groups \(<\) 60. Figure 2A shows the main frequencies profile for CL \(<\) 60, where the main brainwave registered was \(\alpha\) with frequencies of 8.01, 8.48, 8.99, and 9.52 Hz. The 8.99 Hz frequency was observed mainly in the right anterior region (Fp2, Fz, F4, F8, Cz, C4, T8 and P8 channels) and in the left posterior region (P3, P7 and O1 channels). The 8.01 and 8.48 Hz were localized mainly in the left anterior region (F7 and T7 channels, and Fp1, Fpz, F3 and C3 channels, respectively). The 9.52 Hz was found in four central posterior channels: Pz, P4, Oz and O2. The frequencies observed in this group show that the brain activity for CL \(<\) 60 fluctuates between 8 and 9.5 Hz. In posterior channels, higher frequencies were found. Figure 2B shows the global wavelet curves profile for CL \(<\) 60 (\(n\) = 6 crossings per channel). In this  
group, the mean global wavelet curve shows a main \(\alpha\) brainwave with a frequency of 8.99 \(\pm\) 1.86 Hz and a power of 0.98 microV\({}^{2}\). The \(\alpha\) power dispersion range was observed between the C3 channel (1.81 SD above average power) and the P7 channel (1.64 SD below average power). A secondary \(\delta\) brainwave was observed with a frequency of 2.38 \(\pm\) 0.50 Hz and a power of 0.20 microV\({}^{2}\). The \(\delta\) power dispersion range was identified between the F7 channel (1.65 SD above average power) and the P7 channel (2.02 SD below average power). Figure 2C represents the power anomalies profile for CL < 60. In this group, the mean power value of the F, T and C channels corresponded to positive anomalies, and the mean power of the P and O channels corresponded to negative anomalies. The mean power of the Fp channels was near zero. The observed anteroposterior power gradient for this group was decreasing (slope = \(-\)0.06; y-intercept = 0.69 SD).  
Figure 2D shows the main frequencies profile for PD < 60, where the main brainwave was \(\delta\) with frequencies of 2.38 and 2.52 Hz. The 2.38 Hz frequency was distributed on  
Figure 2: Global wavelet profiles of CL and PD men groups < 60. For CL, (**A**) the main frequencies profile, (**B**) the global wavelet curves profile, and (**C**) the power anomalies profile (linear regression y = \(-\)0.062x + 0.69). For men with PD, (**D**) the main frequencies profile, (**E**) the global wavelet curves profile, and (**F**) the power anomalies profile (linear regression y = 0.13x \(-\) 1.4). Channel labels: Fp (frontpolar), F (rontal), C (central), T (temporal) and O (occipital).  
the Fp channels and some posterior regions (P7, P8, O1 and Oz channels). The 2.52 Hz frequency was observed in almost all brain regions (F, T, C, P3, Pz, P4 and O2 channels). The frequencies observed in this group show that the main brain activity for men PD < 60 corresponds to slow waves of around 2.4 Hz. Figure 2E represents the global wavelet curves profile for PD < 60 (\(n\) = 6 crossings per channel). The mean global wavelet curve shows a main \(\delta\) brainwave with a frequency value of 2.52 \(\pm\) 1.05 Hz and a power of 0.90 microV\({}^{2}\). The \(\delta\) power dispersion range was identified between the F7 channel (1.70 SD above average power) and the O2 channel (2.24 SD below average power). The secondary brainwave observed was \(\alpha\), with a frequency value of 8.48 \(\pm\) 2.22 Hz and a power of 0.33 microV\({}^{2}\). The \(\alpha\) power dispersion range was identified between the O2 channel (2.35 SD above average power) and the Fp1 channel (1.20 SD below average power). Figure 2F shows the power anomalies profile for PD < 60. The mean power values of the P and O channels showed positive anomalies, while the mean power values of the Fp, F, T, and C channels presented negative anomalies. The observed anteroposterior power gradient was increasing (slope = 0.13; y-intercept = \(-\)1.4 SD).
