Cortical Dynamics of Neural-Connectivity Fields
Gerald K. Cooray, Vernon Cooray, Karl J. Friston
Macroscopic studies of cortical tissue reveal a prevalence of oscillatory activity, that reflect a fine tuning of neural interactions. This research extends neural field theories b…
Canonical Cortical Field Theories
Gerald K. Cooray, Vernon Cooray, Karl Friston
We characterise the dynamics of neuronal activity, in terms of field theory, using neural units placed on a 2D-lattice modelling the cortical surface. The electrical activity of ne…
Modelling cortical network dynamics
Gerald K. Cooray, Richard E. Rosch, Karl J. Friston
We consider the theoretical constraints on interactions between coupled cortical columns. Each column comprises a set of neural populations, where each population is modelled as a…
Global dynamics of neural mass models
Gerald Cooray, Richard Rosch, Karl Friston
Neural mass models are used to simulate cortical dynamics and to explain the electrical and magnetic fields measured using electro- and magnetoencephalography. Simulations evince a…
Bayesian Belief Updating of Spatiotemporal Seizure Dynamics
Gerald K Cooray, Richard Rosch, Torsten Baldeweg +3
Epileptic seizure activity shows complicated dynamics in both space and time. To understand the evolution and propagation of seizures spatially extended sets of data need to be ana…
Approximate Bayesian inference as a gauge theory
Biswa Sengupta, Karl Friston
In a published paper [Sengupta, 2016], we have proposed that the brain (and other self-organized biological and artificial systems) can be characterized via the mathematical appara…
