Prenatal Development of Ocular Dominance and Orientation Maps in a Self-Organizing Model of V1 (2006)

How orientation and ocular-dominance maps develop before visual experience begins is controversial. Possible influences include molecular signals and spontaneous activity, but their contributions remain unclear. This paper presents LISSOM simulations suggesting that previsual spontaneous activity alone is sufficient for realistic OR and OD maps to develop. Individual maps develop robustly with various previsual patterns, and are aided by background noise. However, joint OR/OD maps depend crucially on how correlated the patterns are between eyes, even over brief initial periods. Therefore, future biological experiments should account for multiple activity sources, and should measure map interactions rather than maps of single features.
