This tells us it's not just
the mechanoreceptors in the skin, but receptors in the ligaments, knuckles, wrist, elbow and shoulder that could be enabling humans to sense minute differences using touch,» he added.
The scientists discovered that a class of
mechanoreceptors in the skin that detect painful mechanical stimuli are part of a feedback circuit in which excitatory neurons that produce the hormone somatostatin are inhibited by neurons that synthesize dynorphin (a natural analgesic molecule that produces effects similar to opiates).
Not exact matches
Yet although these advances have restored a rudimentary sense of touch, the sensors and signals are very different from those sent by
mechanoreceptors, natural touch sensors
in the skin.
Inspired by natural
mechanoreceptors, researchers led by Zhenan Bao, a chemical engineer at Stanford University
in Palo Alto, California, set out to make sensors that churn out digital signals directly.
The 2 - minute rest period may have allowed for a reduction
in deep
mechanoreceptor activation, leading to a restoration of the H - reflex, allowing for normal force production.
