Abstract :
Dimensional complexity of hippocampal EEG of rats under during REM sleep is calculated for varying embedded dimensions. Results show that EEG data recorded from region CA1 and dentate gyrus show similar behavior within the context of nonlinear dynamics. For some animals, however, the EEG recordings from dentate gyrus exhibit denser distribution of reconstructed state vectors in phase space
