Abstract: It includes the steps of (1) preparing step; (2) anesthetizing step; (3) electrodes installing step; and (4) focal onset seizures inducing step. First, a live animal is anesthetized. The electrodes are installed on a working zone of its brain. A first chemical liquid is injected beneath the cerebral cortex of this animal. At two different times, a first electric stimulation and a second electric stimulation are activated by the controller respectively so as to generate a first and a second focal onset seizure accordingly. Thus, it can generate focal onset seizures. It is easy to change the electric stimulation position, numbers and type. In addition, the survival rate of a larger-sized animal after anesthesia is higher.

Abstract: A method comprises steps of capturing first images for displaying a three-dimensional brain structure, capturing second images for displaying blood vessels of the brain and capturing third images displaying implanted electrodes in the brain. These second images are set as standards to respectively adjust and align the first images and the third images. Contrast of the blood vessels is enhanced and the blood vessels are colored with a first color. Contrast of the electrodes is enhanced and the electrodes are colored with a second color. The aligned first images, the colored second images and the colored third images are integrated to obtain integrated viewable information of a brain, (intracranial) electrodes and blood vessels for medical reference. So, spatial positions of implanted electrodes and blood vessels of brains can be confirmed before conducting a medical surgery. And, the physicians can avoid bleeding problem due to accidental touch on blood vessels.
