Single-trial Neuroimaging: Identifying Neural Correlates of Trial-to- Trial Behavioral Variability
Single-trial analysis of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) data potentially enables identification and characterization of neural activity responsible for trial-to-trial behavioral variability -- e.g. variability in response accuracy and/or response time. In this talk I will describe current research in single-trial analysis of neuroimaging data, with emphasis on our work using rapid serial visual presentation (RSVP) as a stimulus paradigm. I will discuss the signal processing methodologies as well as our specific findings regarding the timing and localization of neural activity associated with perceptual processing and decision making. I will conclude by presenting results from our work in single-trial analysis of simultaneously acquired EEG and fMRI.
