Physiology & Behavior
|January 1, 1987
Summary
Researchers developed a simple, noninvasive device for precise measurement of stimulus onset time in gustatory research. It uses a micro-thermistor to detect fluid flow cooling on the tongue.
Area of Science:
- Sensory science
- Neuroscience
- Biomedical engineering
Background:
- Precise timing of stimuli is crucial for gustatory research.
- Existing methods for measuring stimulus onset can be invasive or lack precision.
Purpose of the Study:
- To describe a novel, simple, and noninvasive device for accurate measurement of stimulus onset time.
- To introduce a new tool for advancing gustatory research.
Main Methods:
- The device employs an ultrafast, self-heated micro-thermistor.
- The micro-thermistor detects the cooling effect caused by a fluid stream applied to the tongue.
Main Results:
- The device provides precise, noninvasive measurement of stimulus onset time.
- It accurately senses the temporal dynamics of fluid delivery in gustatory studies.
Conclusions:
- This simple device offers a valuable tool for improving the accuracy and noninvasiveness of gustatory research.
- It facilitates more reliable investigations into taste perception and neural responses.

01:43Gustation
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
01:24The Physiology of Taste
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the diffusion of...
01:14Conditioned Taste Aversion
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single exposure...
