  • Page 4: Introduction

    System Description The NeuroPort System is designed to record and process neural signals from up to 256 surface or penetrating electrodes in addition to auxiliary analog signals and digital experimental events. The system can perform real-time signal processing algorithms on neural signals, including noise cancellation, digital filtering, simultaneous extraction of spike and field potentials, and manual and automatic online spike sorting.
