Development of correlation between left- and right-eye maps for a two-stage simulation. Binocular ORI develops in the first stage, for which only CORI+ = M is non-zero. If CORI−remains zero (no symbol), the correlation rises monotonically and is near 1 within 40 steps. Open symbols show cases in which CORI− = CORI+ in a second stage, beginning at t1; this means that the two eyes’ ORI maps develop independently in this stage. For t1 ≥ 26, the correlated first-stage development has already created conditions such that each eye’s map, developing independently, will converge on a similar map. Thus, the correlation between the two eyes’ maps increases monotonically to a value near 1.
