question 31

Multiple Choice

• A)The receptor potential in neurons X and Z will be more depolarized than in neuron Y.
• B)It won't be possible to discriminate which neuron's receptive field was stimulated at its center.
• C)The frequency of action potentials in the afferent pathway from neuron Y will be increased by excitatory interneurons projecting from the afferent pathways from neurons X and Z. 
• D)The frequency of action potentials in neuron Y will be greater than that in neurons X and Z.
• E)The receptor potentials in all three neurons will achieve the same,average value.
