Effect of Low-Level Laser Stimulation on EEG

Figure 4

The statistic analysis of the theta band (4–7 Hz) by comparing the baseline and each session in laser and placebo group is shown in different areas: (a) C3-P3, (b) C4-P4, (c) P3-O1, (d) P4-O2, (e) T3-T5, and (f) T4-T6. Paired-sample t-test on the theta band power of EEG, comparing each session with the first session (baseline). *P < 0.05 by paired-sample t-test. **P < 0.01 by paired-sample t-test.
