PURPOSE To develop a non-invasive method for exploring seizure initiation and propagation in the brain of intact experimental animals. METHODS We have developed and applied a model-independent statistical method--Hierarchical Cluster Analysis (HCA)--for analyzing BOLD-fMRI data following administration of pentylenetetrazol (PTZ) to intact rats. HCA clusters voxels into groups that share similar time courses and magnitudes of signal change, without any assumptions about when and/or where the… CONTINUE READING
