30.About the physiologic anatomy of nociception, which one of the following statements is NOT correct?
(A)First-order (primary afferent) nociceptive neurons are sensory neurons that are specialized to detect the presence and signal the location, quality, and intensity of tissue-damaging stimuli.
(B)The cell bodies of primary afferent nociceptive neurons are located in dorsal root ganglia and trigeminal ganglia.
(C)WDR neurons encode the intensity of inputs over the entire range of innocuous and noxious stimuli, whereas nociceptive-specific neurons do respond to innocuous stimuli.
(D)After initial synaptic processing at the spinal segmental level, nociceptive information is carried to the brain by direct axonal projections to the thalamus, brainstem and hypothalamus/forebrain.
(E)The primary somatosensory cortex (SI) is located in the postcentral gyrus and extends from the interhemispheric fissure to the sylvian fissure.
