### Global Wavelet Profiles of Control and Parkinson's Disease Men over 60 Years Old (>60)  
Figure 3 shows the general wavelet profiles of the CL and PD groups > 60. Figure 3A shows the main frequencies profile for CL > 60, where two main brainwaves were observed, \(\delta\) and \(\alpha\). The \(\delta\) brainwave was registered on anterior channels with frequency values of 2.38 and 2.52 Hz. The 2.38 Hz frequency was found through all Fp and F channels, except channel F8. The 2.52 Hz frequency was only observed in the Cz channel. The \(\alpha\) brainwave was mainly found on the middle and posterior channels with frequency values of 8.99 and 9.52 Hz. Both \(\alpha\) frequencies were very spread out; the 8.99 Hz was observed on the F8, C3, C4, T8, P7, O1 and Oz channels, and the 9.52 Hz frequency was registered on the T7, P3, Pz, P4, P8 and O2 channels. These observations indicate that the brain activity for men CL > 60 is slower on anterior channels (around 2.4 Hz) and faster on posterior channels (around 9 Hz). Figure 3B is the global wavelet curves profile for CL > 60 (\(n\) = 6 crossing per channel). In this group, the mean global wavelet curve shows notably \(\delta\) and a brainwaves with similar power values, 0.69 and 0.78 microV\({}^{2}\), respectively. The frequency value for the \(\delta\) brainwave was 2.52 \(\pm\) 0.98 Hz, and for the \(\alpha\) brainwave, it was 8.99 \(\pm\) 2.34 Hz. In this profile, the \(\delta\) power dispersion range was identified between the F7 channel (1.36 SD above average power) and the O1 channel (1.78 SD below average power). The \(\alpha\) power dispersion range was found between the O2 channel (0.90 SD above average power) and the Fp1 channel (2.27 SD below average power). Figure 3C represents the power anomalies profile for CL > 60. The mean power value of the F, T and C channels had positive anomalies, and the mean power value of the Fp, P and O channels had negative anomalies. The observed anteroposterior power gradient was decreasing (slope = \(-\)0.04; y-intercept = 0.46 SD). Figure 3D is the main frequencies profile for PD > 60. In this group, two slow brainwaves were observed, \(\delta\) and \(\theta\). The \(\delta\) brainwave showed frequency values of 2.38 and 2.52 Hz, while the \(\theta\) brainwave showed frequency values of 4.24, 6.36, 6.73 and 7.13 Hz. The 2.38 Hz frequency was only observed on the Fp2, F7 and T8 channels. The 2.52 Hz frequency was widely distributed on the Fp1, F8, C, P3, Pz, P4, P8, O1 and Oz channels. The 4.24 Hz frequency was only observed on the  
quency values were 4.00 \(\pm\) 0.70 and 6.73 \(\pm\) 3.27 Hz, with powers of 0.53 and 0.69 microV\({}^{2}\), respectively. The power dispersion range of the 4 Hz frequency oscillated between the O2 channel (2.54 SD above average power) and the T8 channel (2.30 SD below average power). The power dispersion range of the 6.73 Hz frequency fluctuated between the F3 channel (1.98 SD above average power) and the T8 channel (1.76 SD below average power). Figure 3F shows the power anomalies profile for PD > 60. The mean power of the Fp, F and C channels showed positive anomalies, while the mean power of the T, P and O channels had negative anomalies. The anteroposterior power gradient was decreasing (slope = \(-\)0.10; y-intercept = 1.1 SD). Figure 3: 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 = \(-\)0.042 x + 0.46). For men with PD: (**D**) the main frequencies profile, (**E**) the global wavelet curves profile, and (**F**) the power anomalies profile (linear regression y = \(-\)0.1 x + 1.1). Channel labels: Fp (frontopolar), F (frontal), C (central), T (temporal) and O (occipital).
