Derivation of a field equation of brain activity
JOURNAL OF BIOLOGICAL PHYSICS 22(2):101–112.
We present a nonlinear field theory of the brain under realistic
anatomical connectivity conditions describing the interaction between
functional units within the brain. This macroscopic field theory
is derived from the quasi-microscopic conversion properties of neural
populations occurring at synapses and somas. Functional units are
treated as inhomogeneities within a nonlinear neural tissue.,
