Abstract
We hypothesize that anterior thalamus, a subcortical center important for seizure expression, exhibits high signal coherence with cortex during a clonic seizure expression. In addition, the partial coherence would not vanish when the effects of an inert center are removed by a partial regression analysis. Generalized seizures are induced in rats (n = 6) using pentylentetrazol (PTZ) and EEG recorded from cortical and subcortical sites. Statistical analysis of coherence and partial coherence indicates that anterior thalamic and cortical EEG are highly coherent during a clonic seizure expression. Coherence analysis can therefore provide details of the pathway for the spread of seizure activities between subcortical and cortical brain.
