Figure 5.
Time components of UV (ψu) and green (ψg) first-order kernels (A, C, and E) and modified log-normal fits to these functions for the same three cells (B, D, and F). The black and gray lines indicate UV and green response, respectively. Error bars indicating the SEM in the time component of the first-order kernels are shown in (A, C, and E). The circles in B, D, and F represent the kernel values fitted. Parameter values obtained from fits to Eq. 6 are: B(a) UV vu = 0.034 mV(C·ms)−1, tu p = 15.7 ms, σu = 0.281, τu d = 10.5 ms, and green vg = 0.032 mV(C·ms)−1, tg p = 15.4 ms, σg = 0.272, τg d = 8.8 ms; B(b) UV vu = 0.051 mV(C·ms)−1, tu p= 16.4 ms, σu = 0.291, τu d = 10.9 ms, and green vg = 0.034 mV(C·ms)−1, tg p = 15.7 ms, σg = 0.283, τg d = 8.8 ms; B(c) UV vu = 0.068 mV(C·ms)−1, tu p = 17.7 ms, σu= 0.300, τu d = 2.9 ms, and green vg = 0.002 mV(C·ms)−1, tg p = 14.7 ms, σg = 0.396, τg d = 1.1 ms.
