### Tests with Five Male Subjects with Different Brain Activity Conditions
During the test, the patient was asked to blink rapidly to analyze how the signal changes with time, as can be seen in Figure 13a, and measure how blinking during the test can affect the incoming signal. Figure 12: (a) Helmet placement, (b) start-up of tests with Subject 2. Figure 13: (a) Time series, (b) FFT plot of Subject 2. In Figure 13b, an unusual increase in theta and gamma waves can be observed; this is due to the blinking requested from the patient during the session. In addition, an accumulation of gamma and beta waves can be observed, which is normal, since the patient did not show signs of ill health. Likewise, the real-time results of the classification of EEG waves during the session are obtained (see Figure 14a). At this stage, the patient was asked to solve mental mathematical problems, and it is possible to observe how gamma waves predominate during this variation of the test. In Figure 14b, it can be observed that the patient has some difficulty maintaining a continuous state of concentration; however, the patient works to remain stable or close to a state without disturbance. * Subject 3  
In Figure 15, we observe Subject 3. The results were different, since he presented a variation in his health status, which is moderately stressed due to his workload. The patient was not subjected to stress during the test. In this experimental test, priority was given to the relaxation phase based on breathing and meditation exercises through various instructions; the relaxation exercises were performed before the test. The test started with a high level of electrical activity, as shown in Figure 16a; these data are consistent with the health status. The frequency spectrum was obtained, as shown in Figure 16b, revealing an accumulation of beta and alpha waves, along with a decrease in gamma waves, which occurs only at the beginning of the test. From these results, it was determined that the patient must be in an alert state since he will have difficulty concentrating and solving problems. Figure 14: (**a**) Band power, (**b**) focus widget of Subject 2. Figure 17a shows the results obtained, as a total dominance of beta and alpha waves is observed, as well as a decrease in gamma waves; this is due to the moderate stress of the patient. Figure 17b shows another result; this is generated after the patient was subjected to the Chameleon-1 helmet test for 5 min, during which the patient was taken through a real-time monitored relaxation therapy, and an improvement in its signals is observed. From these results, it was possible to maintain a continuous state of relaxation during the last 3 min without difficulty. Figure 16: (a) Time series, (b) FFT plot of Subject 3. Figure 15: (a) Helmet placement, (b) start-up of tests with Subject 3. * Subject 4  
In this test, the patient exhibits a state of moderate insomnia due to a reduced sleep cycle (see Figure 18a). An interview was conducted to confirm his health prior to the test. In this test, the relaxation phase was prioritized based on breathing exercises and meditation based on several instructions, which were explained to the patient before the tests. There was no consumption of any type of drink or energizer that could modify his state of moderate insomnia. Figure 10:0 (**a**) Band power, (**b**) focus widget of Subject 3. Figure 10:1 (**a**) Helmet placement, (**b**) start-up of tests with Subject 4. The test began with a low level of electrical activity, as shown in Figure 19a. These data suggest a possible relationship with the patient's health status, as the wave amplitude appears to be slightly below the range considered healthy in several observed periods. After 2 min, the test samples are taken and the results are shown in a graph of amplitude versus frequency, as seen in Figure 19b. Likewise, an absence of delta waves and a significant presence of theta waves can be observed, suggesting a state of fatigue in the patient. There is also an accumulation of beta and alpha waves as well as a decrease in gamma waves (only at the beginning of the test).
