Control action potential parameters derived from stable recordings obtained from 27 BC of the same batch of EBs. The information is sorted by the APD30–40/APD70–80 ratio (from the smallest [top] to the largest [bottom]). Age: number of days post-differentiation. The corresponding AP traces are pictured in Figure 2 . cAPD90-B (Bazett’s correction); cAPD90-H (Hodge’s correction); cAPD90-Fri (Fridericia’s correction); cAPD90-Fra (Framingham correction).
