Definition

Neural decoding refers to the process of transforming measured neural activity from its original, usually high-dimensional, domain of representation to a new domain that is typically of much lower dimension.

Detailed Description

Overview

In information theory, “decoding” means reversing an “encoding” process that was used to encrypt a set of information-bearing signals in a new domain, usually of lower dimension, where the information is fully preserved. In neuroscience, “encoding” is concerned with the neural representation of behavioral covariates (e.g., sensory inputs, motor outputs, or other cognitive processes). As such, neural decoding is concerned with the process of off-line extraction of information about these behavioral covariates from the measured neural activity (Dayan and Abbott 2005; Wallisch et al. 2008).

The definition of neural decoding, however, has evolved since the introduction of neuromotor prosthesis (NMP) in which neural activity is measured and...
