State-Space Modeling for Single-Trial Evoked Potential Estimation

Abstract

The exploration of brain responses following environmental inputs or in the context of dynamic cognitive changes is crucial for better understanding the central nervous system (CNS). However, the limited signal-to-noise ratio of non-invasive brain signals, such as evoked potentials (EPs), makes the detection of single-trial events a difficult estimation task. In this chapter, focus is given on the state-space approach for modeling brain responses following stimulation of the CNS.
