From the thalamic nucleus, the sensory afferents are projected to the cortical sensory areas, where information is integrated and analyzed.īrodal A. The latter tracts are not discussed in this article in detail because they carry information that is not perceived consciously. ![]() The fibers are then either conveyed to the thalamus (where the third-order neurons are located) or conveyed to the cerebellum. The medulla contains the second-order neurons for fibers carrying touch, position, and vibratory sensations. Note that second-order neuron cell bodies are located in different anatomical areas depending on the sensation they carry.īroadly, the spinal cord contains the second-order neurons for the fibers carrying pain, touch, and temperature sensations. Their axons then travel through the spinal cord either in an ipsilateral or a contralateral fashion. Impulses are carried from receptors via sensory afferents to the dorsal root ganglia, where the cell bodies of the first-order neurons are located.
