Which best describes lateral inhibition in the somatic sensory system?
A. The precision of locating a stimulus is increased by inhibiting signaling along nearby, parallel pathways.
B. The precision of locating a stimulus is enhanced by increasing the frequency of action potentials in nearby, parallel pathways.
C. The frequency of action potentials along pathways from the site of a stimulus is increased by lateral inhibition.
D. Stimuli of one particular modality in a region of the body block transmission of action potentials coding for other modalities generated in the same region of the body.
E. Lateral inhibition reduces the contrast between the frequency of action potentials generated at the center of a stimulus and the frequency of action potentials in surrounding pathways.
