Definition

The local field potential (LFP) is believed to represent the aggregated neuronal activity of populations of neurons. LFP activity encodes information related to the control of movements as well as information about sensory and other cognitive processes. LFP decoding refers to the process of extracting features of these processes from the measured LFP signals. LFP decoding is typically performed for a brain-machine interface application to allow control of an external device such as a prosthetic limb or a cursor on a screen.

Detailed Description

Overview

Neuromotor prosthesis is a class of brain-machine interfaces (BMIs) that aims to restore lost motor function by decoding control information from neural signals. The local field potential (LFP) is one such neural signal that can be utilized. The LFP is operationally defined as the low-frequency components (<~300 Hz) of neural activity recorded extracellularly using microelectrodes and...
