Figure 6. Boxplots (A-C) showing the distribution of kappa values in 5-second increments for regions with high frequency (at the 30% cut off) LIA, LRA and FF respectively compared to the result after 30-seconds. Kappa values for the LIA, LRA and FF are shown at 1-second increments in (D) showing the point at which the kappa value (representing a very good level of agreement) reaches 0.8. LIA: Localised irregular activation, LRA: Localised rotational activation, FF: Focal firing.
