The Model
Brain Resource International Database Brain Resource Ltd. Spinoff 2001, ASX listed. Approx. $40M market cap. Database of circa 30 000 subjects, aged 6-80+. Approx. 50 functional measures per subject + MRI. Excellent statistics. Customers and labs in circa 10 countries. 1st fully standardized international brain function database. Access via BRAINnet.
Inversion
Absence Seizures Linear instability at 3 Hz. Ramping se up and down yields start and end of ‘spike and wave’ oscillations via supercritical Hopf bifurcation.
Ocular Dominance and Orientation Preference
Gamma Oscillations, Binding
Gamma Resonances from Patchy Propagators
Arousal Dynamics How does the brain move between arousal states? Develop and apply a quantitative, physiologically-based model of arousal dynamics, with parameters from experiment. Brainstem ascending arousal system must be integrated, plus circadian oscillations. Physiological Modeling and Parameter Constraints
Model Dynamics
Orexin, Narcolepsy, and Modafinil
