ABSTRACT:
We have combined earlier correlation-based models of striate ocular
dominance and orientation preference map formation into a joint model.
Cortical feature preferences are defined through patterns of synaptic
connectivity to LGN cells which develop due to firing correlations of
those LGN cells. Model parameters include spatial correlation
patterns between ON- and OFF-center cells in separate eye layers of
the LGN. A linear transformation yields correlation functions which
predict whether orientation preferences, ocular dominance, or both,
will develop. The model thus predicts the correlations between LGN
cells which would be necessary to explain formation of visual maps by
a linear process.
