Relating EEG/fMRI to behavior using multivariate pattern classifiers, statistical decision theory and ideal observer analysis

Both electro-encephalography (EEG) and functional magnetic resonance imaging (fMRI) techniques are used in the laboratory with computional tools (single trial techniques,computational approaches to analyis- statistical decision theory and ideal observer analysis) to attempt to integrate neural measures with behavioral data and modeling. Much of the approach is inspired by animal electrophysiology relating single trial neural activity to perceptual choices. The topics investigated range from: 1. Basic science questions in perceptual decision making, visual search, attention and learning; 2. Methods questions involving comparison of MVPA methods/fMRI designs and use of ideal observers for task normalization of pattern classifier performance. 3. Applications such as EEG person identification, detection of attentional failures and multi-brain computing. Research is conducted as part of the Neuro-Group at the UC Santa Barbara/MIT/Caltech Institute for Collaborative Biotechnologies housed on campus.
