Figure 12. Quantum bumps in trpl photoreceptors.

A, average bump from a typical trpl photoreceptor (continuous trace) compared to that in wild-type. Although very similar, the trpl bump has a slightly slower decay phase. B, comparison of the various bump parameters (t₁-t₃ and J_max) between WT (n = 7) and trpl (n = 9 photoreceptors). Each value is the mean and s.d. (across cells) of data measured in 7 WT photoreceptors or 9 trpl photoreceptors. Values in each cell are based on between 100 and 400 bumps. Only values for decay time t₃ were significantly different (Student's t test, P < 0.05). All other values were statistically indistinguishable.
