Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one. It is often tested with two sharp points during a neurological examination [1]: 632 [2]: 71 and is assumed to reflect how finely innervated an area of skin is. In clinical settings, two-point discrimination ...
An esthesiometer (British spelling aesthesiometer) is a device for measuring the tactile sensitivity of the skin (or mouth, or eye, etc.). The measure of the degree of tactile sensitivity is called aesthesiometry. The device was invented by Edward Henry Sieveking. There are different types of aesthesiometers depending on their particular function.
Tactile discrimination is the ability to differentiate information through the sense of touch. The somatosensory system is the nervous system pathway that is responsible for this essential survival ability used in adaptation. [1] There are various types of tactile discrimination. One of the most well known and most researched is two-point ...
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [1] The main functions of the somatosensory system are the perception of external ...
Discrimination testing is a technique employed in sensory analysis to determine whether there is a detectable difference among two or more products. Markovian discrimination is a method used in spam filters to model the statistical behaviors of spam and nonspam. Net bias (also called data discrimination) is the differentiation of price or ...
The 2-point try's failure added an additional obstacle in New York's quest to overcome the 14-point fourth-quarter deficit it faced against Pittsburgh. Still, the Giants still had a chance to ...
Discrimination testing is a technique employed in sensory analysis to determine whether there is a detectable difference among two or more products. The test uses a group of assessors (panellists) with a degree of training appropriate to the complexity of the test to discriminate from one product to another through one of a variety of experimental designs.
