  A review about spinor fields is presented, constructing a outlook through the
last century. Spinor was explored in many contexts more and more in the last
decades. Besides this, more papers about this issue has been produced in the
last decade than in the others before it. As examples, classifications of
spinor fields on the bulk and on compactified seven-manifolds done by the
author are revised and some results about spinor fields on this contexts are
explored, like generating of brane by singular spinors in the bulk, invariants
on five-dimensional black holes and spectral decomposition of a quantum field
on compactified dimensions at low energies.
