ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************

In a way she was shocked by the monofilament line.  When it comes down to it, don't all sensations result in an electrochemical (nerve) impulse?  And this is one reason why it is hard to differentiate between different effects - particularly at extremes (pain is pain whether caused by cold or heat - thus dry ice "burns" like fire...when in actuality it never burns, we just have trouble differentiating the pain).
