Reduced Variability of Auditory Alpha Activity in Chronic Tinnitus

Figure 2

Alpha power group comparison. The bar plots demonstrate the group difference for the temporal alpha power for the lower alpha band from 8 to 10 Hz (a) and the upper alpha band from 10 to 12 Hz (b). The group difference is only significant for the lower alpha frequency range with 𝑃=0.0036.

(a) Low alpha (8–10 Hz)

(b) High alpha (10–12 Hz)
