Figure 9.
IPI histogram and qqplots resulting from executing the code-driven and the open-loop protocols, as compared to the control session. (A) IPIs discharged during the first control session (A dashed line) and the code-driven stimulation session (A solid line). (C) IPIs discharged during the second control session (C dashed line) and the open-loop stimulation session (C solid line). IPIs, represented on the X axis, were in the range between 0 and 400 ms and the probability, represented in the Y axis, was normalized. The qqplots represent the IPI distribution during control session vs. the IPI distribution during code-driven stimulation sessions (B) and open-loop sessions (D). In both qqplots the black line represents the reference line y = x. See an additional example in Figure S4.
