Experimental Study on Epilepsy Treatment Using Electrical Stimulation of the Pig Motor Cortex Based on Deep Brain Stimulation

Abstract

Epilepsy is a common chronic brain disorder, affecting approximately 50 million people worldwide, with over 9 million patients in China. Current treatment methods primarily include drug therapy and surgical intervention. However, drug therapy is often associated with long treatment cycles and significant side effects, while deep brain stimulation (DBS) technology, due to its safety and efficacy, has gradually become the preferred surgical option. This paper, based on deep brain stimulation technology, explores how to achieve targeted current in specific brain regions while minimizing impact on other critical areas through multi-electrode stimulation of the pig motor cortex. The experiment utilizes an adjustable power supply to precisely control current, voltage, and frequency, ensuring the accuracy and safety of electrical stimulation. The results demonstrate that optimizing electrode placement and stimulation parameters can significantly enhance current flow in targeted brain regions. This study provides new insights for the treatment of neurological disorders.
