nursing home experimentation time ! Go operate some red-hot water , either in a sinkhole or tub , and stick your hand under it .
Some of you might be mad at me — the urine was hot and you have no idea why I ask you to scald yourself . ( We ’ll work through this . ) Some of you , though , are going to be a small confused . You know the water was blistering , but when you put your hand under it , it mat up ice cold .
All together now , in your best Jerry Seinfeld vocalisation : " What ’s the peck with that?“
Feeling Spots
Our hands have a great deal of sensory sensory receptor that all receive different ace . These receptors get off sign to the brain to help us make sense of what we ’re touching . We ’ve start some receptor that receive sense impression of cold ( cold spots ) and others that get fondness ( fond spot ) .
Neither of these temperature sense organ draw in double - tariff . If you touch a cold-blooded spot with something hot , it ’s still go to do what it ’s supposed to do : post a cold signal . If you touch a warm spot with something cold , it ’s still go to tell the brain that you ’re touching something warm .
Mixed Signals
neurologist call instances when these musca volitans send the " wrong" signal in reception to a stimulusparadoxical coldandparadoxical passion . If you want to render another experimentation ( and you still trust me after the hot water affair ) , grab a pen andlightlypoke the point around between your metacarpophalangeal joint . In some spots it will experience cold , in some it will feel fond .
Of course , when you guide your hand under spicy water supply , the body of water come to both warm and cold-blooded point . In case like this , where the stimulus is potent enough , the receptor get confused and sometimes the wrong sign gets sent to the nous , even though both temperature receptor are being cause . Sometimes it only takes a second for things to discipline themselves ; sometimes it takes a few minutes .
How did the red-hot water experiment call on out for you ?
