This open access text aims at giving you the simplest possible introduction to differential
equations that are used in models of electrophysiology. It covers models at several spatial and
temporal scales with associated numerical methods. The text demonstrates that a very limited
number of fundamental techniques can be used to define numerical methods for equations ranging
from ridiculously simple to extremely complex systems of partial differential equations. Every
method is implemented in Matlab and the codes are freely available online. By using these codes
the reader becomes familiar with classical models of electrophysiology like the cable equation
the monodomain model and the bidomain model. But modern models that have just started to gain
attention in the field of computational electrophysiology are also presented. If you just want
to read one book it should probably not be this one but if you want a simple introduction to
a complex field it is worth considering the present text.
