correlated with eyeball movement (as in REM sleep) and obtained by
electrodes suitably placed on the skin near the eye) to study nystagmus (a
rapid involuntary oscillation of the eyeballs occurring normally with

| Ergotamine |
|
drug originally derived from the
ergot fungus. Constricts blood vessels and has been used since the 1920's
to treat migraine headaches. They are used to treat
severe, throbbing headaches, such as migraine and cluster headaches.
Dihydroergotamine and ergotamine are not ordinary pain relievers. They
will not relieve any kind of pain other than throbbing headaches. Because
these medicines can cause serious side effects, they are usually used for
patients whose headaches are not relieved by acetaminophen, aspirin, or
other pain relievers. |
