I m studying on experimental models of epilepsy especially chemical model with PTZ. I want to calculate seizure thresholds. Please give me clear information about it.
Pentylenetetrazole (PTZ) is administered in a dose of 90-100 mg / kg to mice at the withers (subcutaneously). The responses to seizures and mortality are recorded within 1-2 hours. Record: the latent time of generalized clonic convulsions, the latent time of tonic-clonic convulsions and the latent time of mortality.
