Refractory period

Refractory period is a period immediately following a stimulus during which further stimulation has no effect. It may specifically refer to:

• Refractory period (physiology), recovery time of an excitable membrane to be ready for a second stimulus once it returns to its resting state, following excitation in the areas of biology, physiology and cardiology
• Refractory period (sex), the recovery phase after orgasm during which it is physiologically impossible for an individual to have additional orgasms
• Psychological refractory period, the delay in response to the second of two closely spaced psychological stimuli
• Postictal state, the period following a series of epileptic seizures during which seizures cannot be induced
