Hello,
Quick question on the relative refractory period in neurons. I understand it is caused by the slow closing of voltage gated K+ channels, which leads to hyperpolarisation. This means a larger than normal stimulus is required to bring the membrane to threshold.
However, after reading my textbook it also says some Voltage gated Na+ channels are slow to open. I read elsewhere that the activation gate is voltage dependent while the inactivation gate is time dependent. How does this contribute to the membrane requiring a greater than normal stimulus?
