Dynamical Adaptation in Photoreceptors

Response to light steps in the dark—comparison of data and DA model predictions.

(A) DA model predictions (using the parameter set B, see Table 2). Step intensities range from 5·10² to 1·10⁷ photons/µm²/s by factors of . (B) Absolute value of peak hyperpolarization and steady-state hyperpolarization against step intensity. The peak response (top, black line) and the steady state response (closed circles) are from Fig. 7 of Ref. [18], and the DA model predictions (red, solid lines) use parameter set B (see Table 2). The gain was set to match the peak response.
