Some Relationships Between Intracranial Pressure and EEG Frequency in Cats ∗

Abstract

Summary

1. In the curarized, unanesthetized cat, the EEG frequency varies inversely with the intracranial pressure. 2. During seizures induced by high partial pressures of oxygen or by Metrazol, the intracranial pressure varies directly with the EEG frequency. 3. No explanation for our findings is offered at present.
