PLV/PAC Feature Extraction Units for Implantable Neural Interfaces: Review

Abstract

Neural interfaces shows promise in treating neurological conditions such as Epilepsy, Depression, and Parkinson's disease. To enable fully implantable treating interfaces, efficient oscillatory feature extraction units are required. This article explores different techniques suggested for extracting phase locking value (PLV) and phase amplitude coupling (PAC) features. Additionally, the article provides an overview of the current state-of-the-art units and highlights their limitations.
