World-volume fields and background coupling of branes
  This is the written version of an invited talk delivered at the workshop ``Quantum gravity in the Southern Cone'' held in San Carlos de Bariloche, Argentina, January 7-10, 1998. After giving a brief introduction to the concept of branes and their role in string theory, this talk describes a method for formulating the dynamics of branes, especially those containing non-scalar moduli. Emphasis is put on the coupling of branes to fields in the low-energy background supergravity theories, and on preservation of maximal amount of manifest symmetry. Due to the nature of the workshop, the presentation is aimed at physicists who are not experts in string theory.
