Dissociation is a robust phenomenon with dramatic and specific clinical meaning, but it has until now been without any secure tie to underlying brain activity. As an initial attempt to formulate a brain model of dissociation, it may therefore be strategically useful to examine some far less dramatic and even commonplace dissociations that occur at the boundaries of major states of consciousness. Many of these dissociative phenomena already have known physiological substrates, and others may constitute more reasonable targets for neurobiological analysis than clinical dissociations. 

Assuming that the interfaces of the active layer act as perfect sinks for the excitons, i.e., all excitons can either recombine or dissociate into free charges at the interfaces, the boundary conditions are n = 0 at x = 0 and x = d.
