= = 1. Suppose that the resting potential of a rod photoreceptor is -30mV and that it responds to a single photon absorption in the dark with the waveform: h(t) = Ate(-t/t), where A =-10uV and 1 = 2 ms. (a) Simulate in MATLAB the rod response to a 100-ms light pulses of 20, 200, and 2000 photons/sec. You can do this using the conv function to convolve the quantum bump with the light stimulus. Note that the stimulus should be stochastic to simulate photon noise. You can assume there is no photoreceptor noise. (b) Plot the rod responses on one graph with a time axis of 200 ms and the light pulse delivered at 25 ms. (c) Describe what happens to the rod response as light intensity is increased. What do you think this means for visual perception? = = 1.
