Question

Quizplus · Accepted Answer

Rods respond to light stimulus by hyperpolarizing, meaning they become more negative and release less neurotransmitter onto bipolar cells, which then transmit the visual signal to the brain. This process is mediated by the activation of photopigments (rhodopsin) in the outer segments of the rods, which leads to the closure of cGMP-gated ion channels and a decrease in intracellular Ca2+ concentration, resulting in hyperpolarization.
