Binocular Rivalry — Mutual Inhibition & Adaptation

Rivalry Model

Input I₁ (eye 1)1.20

Input I₂ (eye 2)1.20

Mutual inhib b1.50

Self-excit a0.50

Levelt II: alternation rate ∝ (I₁+I₂). Levelt IV: rate ∝ |I₁−I₂|. Balance determines if rivalry occurs.

Adaptation

Adapt strength g0.80

Adapt τ (s)3.0

Neural τ (ms)50

Noise σ0.15

Adaptation drives alternations: active percept adapts until suppressed percept wins. τ_A sets dominance duration.

Distribution

Gamma distribution fit (2 params) expected for dominance durations — a signature of neural noise + adaptation interaction. Right panel shows dominance duration histogram. Levelt's propositions: tested by varying I₁ vs I₂.
