Figure 2. Probability of unprovoked seizures following severe lateral FPI.

Figure 2

A) The cumulative probability of detecting unprovoked epileptiform ECoG events in post-FPI (filled circles) and sham-injured (hollow squares) rats is plotted versus time after injury. The incidence of unprovoked seizures in the sham-injured CD Sprague-Dawley rats used for this study is zero up to 4.5 months post-surgery (5.5 months old). B) The cumulative probability of developing grade 1 (filled squares), grade 2 (filled circles), and grade 3 (hollow triangles) seizures by chronic ECoG is plotted versus time after injury. The temporal increase in probability of developing each seizure type had half time τ1=1.1 weeks for grade 1 seizures, τ2=3.0 weeks for grade 2, and τ3=2.8 weeks for grade 3 seizures.
