Multi-scale analysis of neural activity in humans: Implications for micro-scale electrocorticography

Electrocorticography grids have been used to study and diagnose neural pathophysiology for over 50 years, and recently have been used for various neural prosthetic applications. Here we provide evidence that micro-scale electrodes are better suited for studying cortical pathology and function, and for implementing neural prostheses.This work compares dynamics in space, time, and frequency of cortical field potentials recorded by three types of...
