Abstract:
Objective To study the extracranial scalp electroencephalography ( EEG ) and intracranial electrocorticography (ECoG) of closed colony New Zealand white rabbits .Methods To record the extracranial scalp EEG and intracranial ECoG of closed colony New Zealand white rabbits , and to compare and analyze the results of those two scanning methods .Results EEG was characteristic of 9-12 c/sαwave and 16-20 c/sβwave with an amplitude of 30-100μV as the basic rhythm .ECoG showed 10-12 c/s αwave and 16-20 c/s βwave with an amplitude of 200-300 μV as the basic rhythm.Anesthesia could attenuate the electrocerebral activity , cause brain tissue hypoxia , and induce δ wave and slow θ wave in ECoG .Conclusions EEG method is a simple , non-invasive and convenient operation , and can be made in rabbits without anesthesia .The recorded EEG waveform is highly consistent with that of ECoG , and may be used as an alternative to the traditional ECoG in neurofunctional studies .
