stop laughing?</DIV>
<DIV><BR></DIV>> But what actually occurs in our brains to allow us<BR>>
to stop laughing? <BR>> spike<BR><BR>Laughing is, perhaps, controlled in a
different part <BR>of our brain, so when other places in our brain go to
<BR>sleep, the laughing center takes over. And viceversa.<BR>Ok this does not
explain anything! <BR>s. <BR><BR>In 1840 a dentist named Horace Wells had the
idea that, <BR>with the recently discovered "exhilarating or laughing gas",
<BR>teeth might be extracted without pain. Under its influence <BR>he had one
of his own teeth pulled in 1844 and afterwards <BR>frequently used it in his
practice. Before a class at the <BR>Massachusetts General Hospital, Wells gave
a demonstration <BR>with a patient. Things did not go too well. The patient
<BR>suffered great pain. Wells became depressed, addicted <BR>(to chloroform,
another anesthetic agent) and in 1848 <BR>committed suicide. More at:<BR><A
