Figure 4

Number of trials with lower beta band peak frequencies during internal singing at two different tones C4 (256 hz) and C5 (512 hz). The controls include the silence (bottom left) randomly presented during singing data collection and the listen periods (right side panels). Data is taken from dates 2009-3-30 (session 1: 1949 days after implantation), 2009-4-03 (session 2: 1953 days after implantation), and 2009-04-06 (session 3: 1946 days after implantation).
