Comparison of potential landscapes of different input thresholds for large inputs. (a)–(c) The two-dimensional potential landscapes for different input thresholds at the zero coherence level, where the strength of stimulus μ₀ = 60 Hz and parameter b = 107.5, 108, and 108.5, respectively. (d)–(f) The two-dimensional potential landscapes for biased input (μ₀ = 55 Hz) and with coherence c′ = 0.06 and parameter b = 107.5, 108, and 108.5, respectively. In all subgraphs, parameters a = 269.5 and D = 3.6 × 10⁻⁷.
