| This thesis is an investigation of an electroencephalographic (EEG) recording technique in normal dogs. Following a review of the basics of EEG, the requirements for a standard EEG protocol for dogs were discussed. As a first step, a new EEG electrode, the subdermal wire electrode (SWE), was evaluated by comparison with two traditional electrodes, the gold cup electrode (GCE) and subdermal needle electrode (SNE), in awake and sedated dogs. In a randomized, blinded, and prospective fashion, the three electrode types were tested over an a-hour recording period. The SWE performance quality was found to be statistically distinct from both GCE and SNE when evaluated by the duration of artifact and the number of unaffected channels. Sedation also had a significant effect on the quality of the recordings. These distinctions may not be clinically important as significance occurred after two hours of recording, and the mean artifact duration was short. |
