Characteristics of dark-adapted rod bipolar cells recorded in Ames media.

<p>Values are mean ± SEM (number of cells).</p>†<p>Flash strength that elicited a half-maximal response.</p>††<p>Hill coefficient describing the flash intensity-response relation.</p>‡<p>Amplitude of a response to a dim flash estimated to elicit approximately 1 R* per rod.</p>†††<p>Dark-adapted sensitivity: flash response amplitude divided by flash strength.
