Rodent seizure models that pathologically and behaviorally recapitulate age-tailored epileptic disorders are used by us and others to advance our understanding of the chronobiology and mechanisms of epileptic seizure emergence and their comorbidities and to investigate potential novel treatment strategies. Obtaining prolonged continuous electroencephalogram (EEG) tracings over months is essential in this line of translational research, particularly to assess the relation between electrographic changes and the development of seizures and their various psychiatric and cognitive comorbidities in models where seizures gradually emerge over weeks following brain insults. Here we describe our approach to electrode implantation and wiring in order to successfully obtain high-quality continuous EEG tracings in rats for prolonged periods. A detailed stepwise methodological description is provided with a special focus on the details that help most in avoiding notorious pitfalls such as premature EEG cable disconnections and a poor signal to noise ratio.
