1/ nobel price 2021 in physiology or medicine was awarded to work on how heat, cold and touch can initiate signals in the nervous system (David Julius and Ardem Patapoutian, 1/n) https://www.nobelprize.org/prizes/medicine/2021/press-release/
2/ one half of the price is going to elucidating the transduction of mechanical forces into nervous impulses.
3/ turns out these touch receptors (the Piezo1 and Piezo2 mechanosensitive ion channel proteins) are key ingredients in the regulation of many internal functions of the body (urination, respiration, blood pressure, skeletal remodeling), and
they form the basis of proprioception
4/ touch and proprioception are a fundamental perception channel. they are fundamental because they are old in evolutionary terms (phylogenetically) and many younger channels are bootstrapped on top of them (grounding).
5/ would you think that a device that lets you learn about proprioception is useful to increase fun, self-awareness, or well-being?
