Figure 6. Correlation between orientation selectivity and spatial frequency selectivity (Simple cells).
The network model generates a correlation pattern (B) for simple cells’ orientation and spatial frequency selectivity. This pattern resembles the pattern from experimental data (A) for simple cells in layer 4Cα in V1. But the correlation pattern (B) for simple cells is very different from the correlation pattern for simple cells’ summed LGN synaptic input currents in (C). The strengths of correlation are indicated by the correlation coefficients written within each figure panel.
