Waves in Neural Media: From Single Neurons to Neural Fields surveys
mathematical models of traveling waves in the brain, ranging from
intracellular waves in single neurons to waves of activity in
large-scale brain networks. The work provides a pedagogical account of
analytical methods for finding traveling wave solutions of the variety
of nonlinear differential equations that arise in such models. These
include regular and singular perturbation methods, weakly nonlinear
analysis, Evans functions and wave stability, homogenization theory and
averaging, and stochastic processes. Also covered in the text are exact
methods of solution where applicable. Historically speaking, the
propagation of action potentials has inspired new mathematics,
particularly with regard to the PDE theory of waves in excitable media.
More recently, continuum neural field models of large-scale brain
networks have generated a new set of interesting mathematical questions
with regard to the solution of nonlocal integro-differential equations.
Advanced graduates, postdoctoral researchers and faculty working in
mathematical biology, theoretical neuroscience, or applied nonlinear
dynamics will find this book to be a valuable resource. The main
prerequisites are an introductory graduate course on ordinary
differential equations or partial differential equations, making this an
accessible and unique contribution to the field of mathematical biology.
