Acute seizure induction in Kcnt1−/− mice and age-matched wild type controls. (a) Threshold stimulus current to evoke a tonic hindlimb extension seizure. Seizure thresholds are reduced in Kcnt1−/− mice compared to wild type (p =< 0.01, Student’s t test). (b) Electroshock seizure survival at high stimulus intensities. Seizures induced by these high currents were associated with high mortality in wild type animals, while Kcnt1−/− mice were relatively protected (Pearson’s χ2 < 0.01). (c) Latency to convulsive seizures (generalized clonus, rearing and falling, or uncontrolled jumping) following administration of PTZ 60 mg/kg i.p. No differences were observed either in time to seizures (p = 0.27, log rank test) or in observations in the pattern and intensity of seizures.
