Abstract

The neurons in the primary visual cortex of mammals have been found to have significant orientation selectivity. In the higher mammals, the neurons with similar preferred orientation clustered together to form a pinwheel-like pattern, which is thought as a strategy to reduce wiring cost. In contrast, the preferred orientation of neurons in rodents are randomly distributed, which is termed as salt-and-pepper map. Why the mammals have such two distinct organizational pattern remains to be explored and this will be important for understanding the principles of the visual information processing in cortex. In this paper, we used a multidimensional scaling (MDS) model to study the spatial distribution of the preferred orientation and retinotopic position with the objective of minimizing wiring cost. Our results suggested that the scatter of retinotopic position in an orientation column was a critical factor on the formation of pinwheel map or salt-and-pepper map; higher mammals with ordered retinotopic position tend to have continuous map while rodents with relatively larger scatter of retinotopic position tend to have random map.
