The thesis is on neural network models of the early visual system. It describes research in four separate areas.
 1. A study of the temporal dynamics of brightness filling-in under visual masking conditions. 
See:  Arrington, K. F. (1994).  The temporal dynamics of brightness filling-in.  Vision Research,  34(24), p. 3371-3387.
 2. A theoretical development of directional filling-in theory with simulation experiments. 
See: Arrington, K. F. (1996).  Directional filling-in.   Neural Computation,  8(2), p. 300-318.
 3. A model of binocular rivalry using nonlinear feedback and slow habituating chemical transmitters. 
This chapter has yet to be submitted for publication elsewhere, but the chapter may be viewed as: Ch. 6  
 4. A model for preserving invariant contrast-ratio information across hierarchical processing layers. 
The research presented in this chapter was done in collaboration with Stephen Grossberg.It has not been published elsewhere.
