Neuroscience and Neuroinformatics

Understanding of brain organization and function Integration of information across many levels

Physical and functional Gene to behavior Microscopic to macroscopic scales

Challenges in brain observation and modeling Structure and organization (imaging) Operational and functional dynamics (temporal/spatial) Physical, functional, and cognitive operation (models)

Challenges in interpreting brain states and dynamics How to create and maintain of integrated views of the

brain for both scientific and clinical purposes?

Human Brain Dynamics Analysis Problem

Understand functional operation of the human cortex Dynamic cortex activation Link to sensory/motor and cognitive activities Multiple experimental paradigms and methods Multiple research, clinical, and medical domains

Need for coupled/integrated modeling and analysis Multi-modal observation (electromagnetic, MR, optical) Physical brain models and theoretical cognitive models

Need for robust tools Complex analysis of large multi-model data Reasoning and interpretation of brain behavior

Problem solving environment for brain analysis

NeuroInformatics Center (NIC) at UO Application of computational science methods to

human neuroscience problems Tools to help understand dynamic brain function Tools to help diagnosis brain-related disorders HPC simulation, large-scale data analysis, visualization

Integration of neuroimaging methods and technology Need for coupled modeling (EEG/ERP, MR analysis) Apply advanced statistical signal analysis (PCA, ICA) Develop computational brain models (FDM, FEM) Build source localization models (dipole, linear inverse) Optimize temporal and spatial resolution

Internet-based capabilities for brain analysis services, data archiving, and data mining

Observing Dynamic Brain Function

Brain activity occurs in cortex Observing brain activity requires

high temporal and spatial resolution Cortex activity generates scalp EEG EEG data (dense-array, 256 channels)

High temporal (1msec) / poor spatial resolution (2D) MR imaging (fMRI, PET)

Good spatial (3D) / poor temporal resolution (~1.0 sec) Want both high temporal and spatial resolution Need to solve source localization problem!!!

Find cortical sources for measured EEG signals

Computational Head Models Source localization requires modeling Goal:

Full physics modeling of human head electromagnetics

Step 1: Head tissue segmentation Obtain accurate tissue geometries

Step 2: Numerical forward solution 3D numerical head model Map current sources to scalp potential

Step 3: Conductivity modeling Inject currents and measure response Find accurate tissue conductivities

Step 4: Source optimization
