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...

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...

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. New approach methodologies (NAMs) are innovative scientific approaches that generate biological data while reducing reliance on traditional vertebrate animal models. As part of the broader effort to implement the principles of...

FAQs
Controlled presentation conditions and standardized instructions make responses more comparable across participants. By keeping stimulus presentation and task explanations consistent, the methodology reduces sources of bias that could otherwise be mistaken for differences in sensory response. This consistency supports reproducibility and helps researchers relate observed reports or choices to stimulus properties rather than procedural variation.
The choice between trained and untrained panels changes what the resulting data emphasize. Trained panels can contribute structured descriptions of sensory experience, whereas untrained participants can provide responses relevant to preference or hedonic evaluation. Selecting the panel therefore depends on whether the study prioritizes characterizing stimulus qualities, measuring evaluative reactions, or examining behavioral differences among individuals.
Hedonic scales, intensity scales, and preference tests capture different response dimensions. Hedonic scales assess evaluative response, intensity scales record perceived strength, and preference tests examine relative choice. Matching the tool to the research question helps researchers distinguish liking-related evaluation, sensory magnitude, and selection behavior rather than treating these outcomes as interchangeable.
Sensory evaluation methodology can connect two sources of variation: properties of the stimulus and differences among people. When participants provide ratings or choices under common conditions, researchers can examine whether responses track changes in the presented stimulus or reflect individual patterns. This distinction is useful because perception and choice may vary even when the evaluation procedure remains consistent.
A basic evaluation workflow begins by identifying the sensory response of interest, selecting controlled presentation conditions, and preparing standardized instructions. Researchers then choose a trained or untrained panel and apply an appropriate rating tool, such as an intensity or hedonic scale. The resulting ratings, discriminations, or preferences can be organized as observable behavioral responses for analysis.
In behavior research, these methods support studies of perception, choice, and individual differences without relying only on informal descriptions of experience. A study may use intensity ratings to quantify perceived strength, preference tests to examine selection, or hedonic ratings to assess evaluative response. Linking these outcomes with stimulus properties provides a structured basis for interpreting how sensory experience relates to behavior.
