Final answer:
In neurobiology, considering an absolute refractory period of 2 msec, the maximum frequency of action potential production in a neuron is 500 action potentials per second.
Step-by-step explanation:
The subject in question is neurobiology, specifically relating to the frequency of action potential production in neurons.
Since the absolute refractory period is given as 2 milliseconds (msec), and during this period no new action potentials can be generated, we can calculate the maximum frequency of action potential generation.
The frequency is the reciprocal of the period, so the maximum frequency with which a neuron can fire is 1/(0.002 seconds), which equals 500 action potentials per second.
