Neuron communication about the strength of a stimulus is conveyed by the Blank______ of action potentials.Multiple choice question.magnitudefrequency

Break Down the Problem

1. Identify the key terms in the question: neuron communication, strength of a stimulus, action potentials.
2. Determine the correct choice between "magnitude" and "frequency."

Relevant Concepts

• In neuroscience, neurons communicate using action potentials. The strength of a stimulus is conveyed by the number of action potentials generated in a given time period, which relates to the frequency of firing rather than the magnitude of the action potentials themselves.

Analysis and Detail

1. Frequency of Action Potentials: When a stimulus is stronger, the neuron fires action potentials more frequently.
2. Magnitude of Action Potentials: The magnitude (or amplitude) of action potentials remains relatively constant; it does not vary with the strength of the stimulus (this is known as the all-or-nothing principle of action potentials).

Verify and Summarize

• Given that stronger stimuli lead to a higher frequency of action potentials, the correct answer emphasizes the frequency at which these potentials are fired.

Final Answer

The correct choice is frequency.
