Exploration of Brain Tumor Localization with High-density Electrocorticography

The fast and accurate detection of brain tumor locations has always been a focus of research in the field of neuroscience. The main emphasis of this paper is to propose a potential intraoperative fast glioma localization technique. This study utilizes the rapid and high temporal resolution characteristics of electrocorticography to investigate the electroactive properties of the glioma region from a functional variability perspective and employs its differences to detect the location of the glioma. Analysis of the two-minute data shows that the structural similarity and cosine similarity of tumor localization can reach 0.8277 and 0.9460 respectively. Additionally, this method can achieve stable average performance similar to the full-length data in a 1-second data length, indicating the potential for this technology to realize real-time automatic glioma localization, and it is expected to be applied in clinical intraoperative settings.
