Which of the following better represents the process of adaptation mediated by the voltage-gated Ca²⁺ channels and Ca²⁺-activated K⁺ channels? The vertical axis in each graph is the membrane potential in the postsynaptic neuron (in millivolts), while the horizontal axis is the time of constant stimulation (in milliseconds).

Question

Quizplus · Accepted Answer

Under constant stimulation, the opening of Ca²⁺-activated K⁺ channels increases K⁺ permeability, making the membrane harder to polarize, increasing the delay between action potential, and decreasing the cellular response.
