Protocol for recording epileptiform discharges of EEG and behavioral seizures in freely moving mice

Recurrent seizures are a common feature in many neurologic disorders. Seizure examination may help with diagnosis, preclinical study, and development of treatment strategies. Here we detail protocols to prepare and implant electrodes, as well as to record and analyze seizure events in freely moving mice. SCA47 mice exhibit both preclinical seizures (i.e., epileptiform discharges of EEG) starting from ∼14 weeks of age and behavioral seizures (i.e., spontaneous behavioral seizures) starting from ∼22 weeks of age.
