We got used to believe the eyes and ears, but not always we realize that the enormous volume of information we get not through them, and through a skin. Touch - most ancient from feelings. Both sight and rumor arose up during an evolution much later. It is set that a human embryo already in a maternal womb is able to feel the surrounding world.Professor of neurology and known popularizer of science David Линден enthrallingly and accessible - literally "on fingers" - explains how the difficult mechanisms of touch work, and in concert takes apart his numerous riddles. Why does a pepper seem to us burning, and mint - cold? Why are afraid of we tickling, if we are tickled by somebody else, and does not react on her, if we try to tickle itself? That actually does take place wherein itches? What does an orgasm fundamentally differ from other muscular crampies, for example sneezes?In a book David Линдена a reader will find answers for these and many other questions.
