Adaptation of Cutaneous Tactile Receptors
نویسنده
چکیده
The potassium content of the skin of Rana pipiens is found to be 132 m.g. per cent. This is roughly of the order of magnitude of the content of potassium in nerve. Analyses were also made of the skin for Na, Ca, Mg, Cl, S, and P.

Adaptation of Cutaneous Tactile Receptors. Ii
Studies of axon potentials set up by pressure stimuli applied to single cutaneous receptors in frog's skin indicate that the mechanical stimulus excites the free nerve endings directly. Adaptation to constant pressures or to intermittently applied pressures (failure of the response) may be due to the reduction of excitability of the nerve endings by potassium released under the pressure from su...
متن کاملAdaptation of Cutaneous Tactile Receptors. Iii by Hudson Hoagland
In a recent paper (Hoagland, 1934-35) evidence was presented indicating that adaptation to pressure as measured by the failure of nerve impulses from single mechanoreceptors in frogs' skin is produced by an inhibitory neurohumor, probably containing potassium, released from cutaneous cells when they are pressed upon. The receptors are axon endings branching among the cutaneous cells. The releas...

Further experimental evidence is presented indicating that the peripheral inhibitory phenomenon known as sensory adaptation, as it is manifested in tactile receptors in frogs' skin, is produced by a neurohumor released by non-nervous cells of the skin when they are pressed upon. 1. Adaptation is not produced by electrically initiated antidromic impulses backfired into the axon branches. 2. Inte...
متن کاملObjective Evaluation of Tactile Sensation for Tactile Communication
We humans use the five senses of “sight, sound, touch, taste and smell,” to interact with other people and various objects around us. While remote communication with video and speech have become familiar to us lately, DoCoMo is currently working on research aiming at finding ways to communicate via tactile sensation, which is believed to be important in terms of information volume, which comes ...
متن کاملWhy wet feels wet? A neurophysiological model of human cutaneous wetness sensitivity.
Although the ability to sense skin wetness and humidity is critical for behavioral and autonomic adaptations, humans are not provided with specific skin receptors for sensing wetness. It has been proposed that we "learn" to perceive the wetness experienced when the skin is in contact with a wet surface or when sweat is produced through a multisensory integration of thermal and tactile inputs ge...
