Source:Tracey A. Milligan, MD; Tamara B. Kaplan, MD; Neurology, Brigham and Women's/Massachusetts General Hospital, Boston, Massachusetts, USA A complete sensory examination consists of testing primary sensory modalities as well as cortical sensory function. Primary sensory modalities include pain, temperature, light touch, vibration, and joint position sense. Sensation of the face is discussed in the videos Cranial Nerves Exam I and II, as are the special senses of smell, vision, taste, and...

Immunocytochemical identification of peripheral sensory nerve fiber subtypes (and detection of protein expression therein) are key to the understanding of molecular mechanisms underlying peripheral sensation. Here we describe methods for preparation of peripheral/visceral tissue samples, such as skin and limb bones, for specific immunostaining of peripheral sensory nerve fibers.

What is a Sensory System?

2019
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position. Sensory systems include the visual, auditory, gustatory (taste), olfactory (smell), somatosensory (touch, pain, temperature, and proprioception), and vestibular...
FAQs
The first critical step is stimulus transduction: specialized receptors respond to mechanical, thermal, or chemical changes and convert them into electrical signals. Those signals then enter peripheral nerve fibers, where action potentials carry the information onward. Separating detection from transmission allows the nervous system to process different kinds of bodily and environmental change.
Action potentials provide the transmission stage between receptor activity and central processing. Once generated in a sensory pathway, they travel along peripheral nerves toward the spinal cord and brain, where the incoming information is interpreted. This route links a local stimulus with sensation and illustrates how sensory nerves support broader neural communication.
Stimulus type matters because receptor specialization determines which changes can be detected and represented in sensory signaling. Mechanical, thermal, and chemical inputs therefore enter the nervous system through distinct forms of initial stimulation, even though their information is ultimately transmitted as electrical activity. This organization supports varied sensations, including touch, temperature, pain, and body position.
These pathways support more than conscious sensation. Sensory information reaches the spinal cord and brain, giving the nervous system input that can contribute to reflexes as well as interpretation of touch, pain, temperature, and body position. Studying the same signaling route therefore connects cellular neural communication with observable responses and perception.
Diagnostic testing can use knowledge of sensory signaling to investigate whether information from receptors and peripheral pathways is reaching the central nervous system appropriately. This perspective is especially relevant when studying neuropathy, in which sensory function may be disrupted. The resulting assessment can help relate reported sensory problems to abnormal neural communication.
Chronic pain research examines how sensory signaling becomes abnormal rather than treating sensation as a simple readout of stimulation. Because sensory pathways carry information from receptors toward the spinal cord and brain, researchers can investigate where altered signaling may affect perception. This work supports treatment approaches designed to target abnormal sensory signaling.
Injury-repair studies focus on restoring effective communication along sensory pathways after damage. Understanding receptors, peripheral nerve fibers, action potentials, and central processing gives researchers a framework for locating which part of signaling requires attention. This biological context helps connect repair experiments with questions about recovering sensation, reflex-related function, and other neural outcomes.
