Figure 5.2 : (A) Average maximum response amplitudes for rods (n=6) and cones (n=3)
averaged over two directions. (B) Maximum response amplitude vs logarithmic light in-
tensity of a whole-field flash stimulus for dark adapted and background light adapted rods
and cones fit with the Hill equation V = A∕(l + (Λ'1∕2∕x)n)∙ (ɑ) Normalized cone response
compared with cone stimulus transformed by cone response sensitivity in B to yield stimulus
intensity. (D) Measured rod response compared with theoretical uncoupled rod response
from transforming stimulus intensity from C with rod sensitivity in B.
