Publication number: 20200178877Abstract: 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.Type: ApplicationFiled: February 22, 2019Publication date: June 11, 2020Inventors: YUE-LOONG HSIN, SYU-JYUN PENG, CHENG-SIU CHANG, FU-YUAN SHIH

Patent number: 10448878Abstract: Many electrodes are positioned inside a skull for obtaining several electric voltage variation wave information. A processing unit computes subtract operation between two neighboring electrical voltage variation wave information respectively and then can obtain electrical voltage difference waves. Furthermore, each electrical voltage difference wave is separated into a first band wave signal and a second band wave signal. After which, several first band wave envelope signals and second band wave envelope signals are obtained. It conducts a co-relation processing about the first band wave envelope signals and the second band wave envelope signals. So, a co-relation table is obtained for determining a position where an intracranial brain wave abnormality occurs. In this invention, a unique scientific approach to determine the spatial position of seizure onset occurred inside the brain. In addition, the position of intracranial brain wave abnormality can be concretized and visualized by the co-relation table.Type: GrantFiled: April 17, 2017Date of Patent: October 22, 2019Assignee: CHUNG SHAN MEDICAL UNIVERSITY HOSPITALInventors: Yue-Loong Hsin, Syu-Jyun Peng

Publication number: 20190102884Abstract: 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.Type: ApplicationFiled: November 29, 2017Publication date: April 4, 2019Inventors: YUE-LOONG HSIN, SYU-JYUN PENG, CHENG-SIU CHANG, FU-YUAN SHIH

Publication number: 20170367608Abstract: An electrode module is positioned inside an intracranial portion of a human head. Then, it captures brain images of the human head so multiples two dimensional (2D) cross-sectional images are obtained. The electrodes can be seen in one or more 2D cross-sectional images. A brain functional map adjusting portion is provided to obtain the 2D cross-sectional images and then to conduct a proportional deformation process for the images in the brain functional map database. By combining the processed images in the brain functional map database and the 2D cross-sectional images, multiple combined cross-sectional images can be obtained for display. So, the effects of intracranial electrodes are better than the traditional way. In addition, the brain structure information of a patient contains the precise positions of the electrodes and the corresponding brain functional areas.Type: ApplicationFiled: January 13, 2017Publication date: December 28, 2017Inventors: YUE-LOONG HSIN, SYU-JYUN PENG
