Abstract
This paper outlines a dynamic theory of development and adaptation in
neural networks with feedback connections. Given input ensemble, the
connections change in strength according to an associative learning
rule and approach a stable state where the neuronal outputs are
decorrelated. We apply this theory to primary visual cortex and
examine the implications of the dynamical decorrelation of the
activities of orientation selective cells by the intracortical
connections. The theory gives a unified and quantitative explanation
of the psychophysical experiments on orientation contrast and
orientation adaptation. Using only one parameter, we achieve good
agreements between the theoretical predictions and the experimental
data.
