Show transcribed image text Some sensory neurons in our bodies generate action potentials in response to pressure or movement, allowing us to feel things through our sense of touch. Based on what you learned, how does such a neuron indicate stimulus strength/intensity? By altering the speed of action potential propagation: Stronger stimuli cause action potentials to travel faster down the axon. By altering the peak membrane potential (V_m) during the action potential: Stronger stimuli produce taller action potentials. By altering the rate of action potential generation: Stronger stimuli produce more frequent action potentials. By altering the amount of neurotransmitter released by the neuron: Stronger stimuli make each action potential release more neurotransmitter. What information does the pain receptor relay to the brain about stimuli BELOW threshold? The duration of the stimulation. The location of the stimulation. The membrane potential at the site of stimulation. None of the above. Which statement below describes how V_m changes overtime during the action potential? At the start of the action potential, V_m quickly becomes more positive, and then it becomes more negative. At the start of the action potential, Vm quickly becomes more negative, and then it becomes more positive. V_m becomes more and more positive with each action potential. V_m usually doesn't change during the action potential.
