    en.wikipedia.org/wiki/Two-point_discrimination

    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.

    The two ascending tracts meet at the level of the sixth thoracic vertebra (T6). Ascending tracts typically have three levels of neurons, namely first-order, second-order, and third-order neurons, that relay information from the physical point of reception to the actual point of interpretation in the brain. Neural connections in the DCML pathway.

  4. Tactile discrimination - Wikipedia

    en.wikipedia.org/wiki/Tactile_discrimination

    Two-point discrimination (2PD) is a neurological examination in which two sharp points are applied to the surface of a part of the body in order to see if the patient recognizes them as two discrete sensations. [2] The two-point threshold is the smallest distance between the two points that the patient can recognize. [17] By conducting this ...

    en.wikipedia.org/wiki/Merkel_nerve_ending

    Merkel nerve endings (also Merkel's disks, [1] or Merkel tactile endings [2]) are mechanoreceptors situated in the basal epidermis as well as around the apical ends or some hair follicles. [2] They are slowly adapting. They have small receptive fields measuring some milimeters in diameter. Most are associated with fast-conducting large ...

    en.wikipedia.org/wiki/Discrimination_(information)

    The texture discrimination task is a common task used in visual perception learning. Two-point discrimination is the ability to discern that two nearby objects touching the skin are distinct. Utrocular discrimination is the ability to tell which of two eyes has been stimulated by light.

  7. Sensory decussation - Wikipedia

    en.wikipedia.org/wiki/Sensory_decussation

    The two nuclei receive the impulse from the two ascending tracts: fasciculus gracilis and fasciculus cuneatus. After the two tracts terminate upon these nuclei, the heavily myelinated fibres arise and ascend anteromedially around the periaqueductal gray as internal arcuate fibres. These fibres decussate (cross) to the contralateral (opposite ...

    The Lions had two shots at the 2-point conversion after that, due to a Cowboys offsides penalty on the first attempt, but Goff threw incomplete on the last attempt and the Cowboys hung on to win ...

    en.wikipedia.org/wiki/Two-alternative_forced_choice

    Two-alternative forced choice (2AFC) is a method for measuring the sensitivity of a person or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input. For example, to determine a person's sensitivity to dim light, the observer would be presented with a ...
