Electrophysiological alterations in a complex rat model of schizophrenia.

•EEG phenotype characterization in a rat substrain related to schizophrenia/autism.•ERPs showed significant changes in P2 latency and N1 amplitude.•Acute ketamine treatment did not cause alterations in ERPs.•Altered power of oscillations in different frequency bands was observed.•Ketamine caused strain-dependent changes in the power of oscillations.
