Can someone please explain to me the difference between the two phototransduction cascades? According to my understanding, rods are used at night (depolarized) and when they are exposed to light, they get activated/hyperpolarized. This results in the bipolar ganglion cells getting depolarized, CGMP --> GMP, Na+ channels close. Is this process correct? Is this process identical to what happens in cones?
Why is hyperpolarization considered activation when you're actually turning off the rods? The terminology is a bit confusing to me.
