Gunther is becoming frustrated with the television in his hotel room. He wants to scan through the channels very rapidly, but each time he switches the channel he has to wait a full two seconds before he can change it again. During that brief delay, it is impossible to change the channel. This is similar to how the works in neural communication. A) regenerative timeout B) potential gradation C) absolute refractory period D) relative refractory period

Absolute refractory period

Explanation:

The absolute refractory period is the period that is started from the initiation period of action potential to the immediately after peak point. This is called the Absolute Refractory Period. This is the time between neuron action potential and not lead the second action potential. The absolute refractory period takes around 1 to 2 minutes.  

Thus here Gunther is becoming frustrated with television in the hotel room. He has been scanned through channels. This is the example of an absolute refractory period.

This is similar to how the ABSOLUTE REFRACTORY PERIOD works in Neural communication.

Explanation: The REFRACTORY period refers to the the period, after excitation, during which a membrane recovers its polarization and is not able to respond to a second stimulus.

In this period, it is impossible to react to stimuli.

A perfect example can be observed in the physiology of a man when having sex and have reached orgasm. The period that which the individual recovers from the orgasm to continue sex is referred to as the absolute refractory period.
