Mathematical Institute, University of Oxford, 24–29 St Giles’, Oxford OX1 3LB, United Kingdom Summary. Modeling brain dynamics requires us to define the behavioral context in which brains interact with the world; to choose appropriate mathematics, here ordinary differential equations (ODE) and random graph theory (RGT); to choose the levels of description and scales in the hierarchy of neurodynamics; to define an appropriate module for each level; and to address questions of boundary conditions, linearity, time-variance, autonomy, and critical- ity. ODE applied to the olfactory system serves to model perception by a phase transition TI - Scale-Free Cortical Planar Networks JF - Handbook of Large-Scale Random Networks DO - 10.1007/978-3-540-69395-6_7 DA - 2008-01-01 UR - https://www.deepdyve.com/lp/unpaywall/scale-free-cortical-planar-networks-8K3HArcVlr DP - DeepDyve ER -
