Figure 5
A topological plot of theta frequency band for three concussion symptoms subgroup. (A) Difficulty concentrating, (B) Pressure in the head, (C) Fatigue and low energy). It displays the difference of power spectral density, between POST and PRE, only for the statistically significant electrodes (0.008 ≤ p ≤ 0.049, represented by a blue star in the figure). Each subgroup presented significant electrodes on the frontal lobe (16 significant electrodes for difficulty concentrating, 15 for pressure in the head, and 14 for fatigue and low energy) for all of them, as well as an increase in the occipital lobe for the Pressure in the head (8 significant electrodes) and Fatigue and low energy (10 significant electrodes) subgroup.
