A Research Strain of Mice Has a Mutation That Causes

question 44

Multiple Choice

A research strain of mice has a mutation that causes voltage-gated sodium channels to take longer to return to the active state after a spike.What is the likely consequence for transduction of sensory stimuli?

• A)There will be no effect on sensory perception, because sensory information relies on stimulus-gated ion channels and not voltage-gated ion channels.
• B)Sensory information will be incorrectly perceived as high intensity stimuli, due to the increased frequency of action potentials.
• C)The mutation will interfere with the ability of stimuli to create receptor potentials, and thus the neuron will fire with slow, broad action potentials, giving the animal enhanced sensory perception.
• D)Due to a longer refractory period, the neuron will be unable to conduct high frequency action potentials, and thus will not effectively transmit information about strong stimuli.
