Abstract :
Brain herniation was induced in a rat model by expansion of a balloon in the epidural space. Somatosensory evoked potentials (SEPs) from median nerve stimulation were recorded on the cranium and analyzed with spectral coherence algorithm. Post-experimental MRI evaluation of the brains was correlated to coherence analysis results.
