========

Understanding-oriented background. These pages explain *why* brainmass is built the way it
is — what a neural mass model is, why a differentiable JAX core matters, how the package is
organized, and the theory behind coupling, delays, and forward models. They complement the
hands-on :doc:`../tutorials/index` and :doc:`../howto/index`.
