Given that action potentials traveling down the axon of a particular neuron are always the same amplitude how is a stronger stimulus communicated to the next cell in the neural pathway?
The strength of a stimulus is coded in the frequency of action potentials, not in the amplitude.
How do action potentials relay intensities of information?
The nervous system can detect the strength of a stimulus by measuring the frequency of action potentials . For example a hard hit might generate 10 impulses per second.
Does strong stimuli cause the strength of action potentials to increase?
No, it doesn't become "larger" - the peak potential is always the same - it is a digital signal. Stronger stimulus will cause the nerve cell to fire more often - therefore stimulus strength is translated as action potential frequency.
Another word for an earthquake's strength is what?
Magnitude.
What are the measure of the strength of an earthquake is called?
The Richter magnitude scale is used to measure the strength of an earthquake.

What does the central nervous system use to determine the strength of a stimulus?
frequncy of action poteinals
What is the Difference between a weak stimulus and intense stimulus?
The FREQUENCY of action potentials that are conducted into the central nervous system serves as the code for the strength of the stimulus. This frequency code is needed because the amplitude of action potentials is constatnt (all or none). Acting through changes in action potential frequency, tonic receptors thus provide information about the relative intensity of a stimulus.

What is an earthquake's strength?
Depends on it's magnitude which can range. Seisometers are used to measure the Magnitude of an earthquake. Magnitude is it's strength.
How does a neuron indicate the strength of a stimulus?
A neuron conveys information about the strength of stimuli by varying the rate in which the stimulus is fired.
Another word for an earthquake's strength is what?
Magnitude.
What is the strength of an earthquake?
Magnitude.
What is the difference between stimulus frequency and stimulus strength?
<P> <P>The stimulus frequency is how often the stimulus is admitted. For example, every 30 seconds, every minute and 1/2, etc. <P>Stimulus strength describes the level of force used to administer the stimulus such as mild, moderate or maximum.</P>
What is a forces magnitude?
The magnitude of a force is its 'size' or 'strength', regardless of its direction.
What scale is used to measure the strength (magnitude) of an earthquake?
Richter Magnitude
