TY - CHAP M1 - Book, Section TI - Disorders of Non-Painful Somatic Sensation A1 - Ropper, Allan H. A1 - Samuels, Martin A. A1 - Klein, Joshua P. A1 - Prasad, Sashank PY - 2019 T2 - Adams and Victor's Principles of Neurology, 11e AB - The preceding chapter dealt with pain and its pathways and mechanisms. There are, of course, several other somatosensory experiences that also utilize specialized end organs, pathways, and neurophysiologic mechanisms; these include touch, vibration and joint position senses, appreciation of deep pressure, as well as integrated sensory experiences that depend on cortical functions and are the subject of the current chapter. The separation between these two broad somatosensory systems is logical in so far as each depends on distinctive tracts in the peripheral nerves, spinal cord, and brain. In clinical practice, however, they are tested in parallel and give complementary information regarding the localization and nature of a lesion. Because the peripheral nervous system is organized in a segmental pattern, the superficial representation of all sensation, nociceptive and non-nociceptive, follows the dermatomal and peripheral nerve map shown in Fig. 8-1.
