Reading the Combine Advisor article on the Overwiki will help, as it explains just what the advisors due to humans -- the same thing the advisor did to Eli. To answer your question, however, the advisor, using its tongue-like probiscis, pierced Eli's cranium, thus incapacitating his central nervous system. Usually, this will kill a person instantly.
