The end-bulbs of Krause were thought to be thermoreceptors, sensing cold temperatures, but in early research their function remained unknown. [3] Recently optogenetic studies revealed their role in sexual stimulation and mating behavior in mice:
The end-bulb of Krause or bulboid corpuscle detects temperatures above body temperature. Ruffini's end organ detects temperatures below body temperature. TRPV1 is a heat-activated channel that acts as a small heat detecting thermometer in the membrane which begins the polarization of the neural fiber when exposed to changes in temperature.
Krause discovered and described mechanoreceptors that were to become known as "Krause's corpuscles", sometimes referred to as "Krause's end-bulbs". [citation needed] His name is also associated with: "Krause's membranes": defined as isotropic bands in striated muscle fiber that consist of disks of sarcoplasm and connect the individual fibrils ...

The Standard Catalog of World Paper Money was a well-known catalogue of banknotes that was published by Krause Publications in three volumes. These catalogues are commonly known in the numismatic trade as the Pick catalogues, as the numbering system was originally compiled by Albert Pick, but are also referred to as "Krause" or "SCWPM". Since ...
[3] 20 to 40 glands of Krause are found in the upper fornix, and 6-8 glands appear in the lower fornix. [4] There are usually 2 to 5 Ciaccio's glands, and are found along the superior tarsal border of the upper eyelid. [1] Popov’s glands are located within the substance of the caruncle. [1]
This spindle-shaped receptor is sensitive to skin stretch, and contributes to the kinesthetic sense of and control of finger position and movement. [3] They are at the highest density around the fingernails where they act in monitoring slippage of objects along the surface of the skin, allowing modulation of grip on an object.
The bulb's "turn on" voltage V b is higher than its "turn off" voltage V e. This property, called hysteresis, allows the bulb to function as an oscillator. Hysteresis is due to the bulb's negative resistance, the fall in voltage with increasing current after breakdown, [7] [14] which is a property of all gas-discharge lamps.
