Figure 4. Relationship between the magnitude of activation in left prefrontal cortex (PFC) and behavioral scores in cochlear implant (CI) users.

Plots of the Pearson correlation r between the magnitude of the mean β value in the left PFC region of interest (ROI) are shown with respect to speech perception score, left ear hearing threshold unaided, left ear hearing threshold (aided if the subject used a hearing aid), and right ear CI-aided hearing threshold. Hearing threshold was defined as four-frequency pure-tone average (4fPTA) at four frequencies, 500, 1000, 2000, and 4000 Hz.

Individual subject (thin lines) and group mean (bold lines) hearing at 250, 500, 1000, 2000, 3000, 4000, and 6000 Hz for (A) left ear unaided, (B) left ear aided, and (C) right ear (unaided for controls and with a cochlear implant [CI] for CI users).
