1 Mitsuo Kawato ATR Computational Neuroscience Labs
Towards Manipulative Neuroscience based on Brain Network Interface ブレインネットワークインタフェースに 基づく操作脳科学を目指して Mitsuo Kawato ATR Computational Neuroscience Labs Discovery Channel

2 Direct Use of Computational Models in Neuroimaging
Brain Imaging Data X Y Z P Q R U V W Model 1 Model 2 Model 3 Visual stimuli and reward sequence Actions taken by subject Behavioral Data

3 Framework of Control (Manipulative) System Neuroscience
Necessity to link theory and experiments, beyond mere temporal correlation of hypothetical theoretical variables with neural firings or brain activation Decoding of neural information by BNI and its feedback to brain Theory-guided manipulation of BNI feedbacks and their predicted effects

4 Hierarchical Bayesian Filter Soft Constraint from fMRI/NIRS data
Hierarchical Baeysian Estimation of Current Distribution from fMRI/MEG Data High temporal resolution (ms) High spatial resolution (mm) time Current Hierarchical Bayesian Filter Estimated Current MEG/EEG data Focus on active region Soft Constraint from fMRI/NIRS data time Current Current Source Temporal average data from fMRI/NIRS

5 Classification of Attend to Motion or Color by Single-trial MEG before Stimulus Presentation
1. Classification at Sensor Space with Sparse Logistic Regression MEG Feature extraction Classification Test : 70.4% (40 features) CV : 78.5 ± 7.7% 2. Classification at Brain Space via VB-MEG Inversion MEG Feature extraction Classification Test : 85.7% (8 features) CV : 90.7 ± 6.9% Source localization
