History
Eric Kandel was one of the first to study the neural basis of sensitization based on his experiments observing gill withdrawal of the seaslug Aplysia in the 1960s and 1970s. Kandel and his colleagues showed that after habituation from siphon touching (gill withdrawal response weakened), applying a paired noxious electrical stimulus to the tail and a touch to the siphon, gill withdrawal was once again noted. After this sensitization, applying a light touch to the siphon, absent of noxious stimulus to the tail, Aplysia produced a strong gill withdrawal response. When tested several days after the initial trials, this response was still manifest (After Squire and Kandel, 1999). In 2000, Eric Kandel was awarded the Nobel Prize in Physiology or Medicine for his research in neuronal learning processes.

Famous quotes containing the word history:
“Three million of such stones would be needed before the work was done. Three million stones of an average weight of 5,000 pounds, every stone cut precisely to fit into its destined place in the great pyramid. From the quarries they pulled the stones across the desert to the banks of the Nile. Never in the history of the world had so great a task been performed. Their faith gave them strength, and their joy gave them song.”
—William Faulkner (1897–1962)
“Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon than the Word of God. It is a history of wickedness that has served to corrupt and brutalize mankind.”
—Thomas Paine (1737–1809)
“English history is all about men liking their fathers, and American history is all about men hating their fathers and trying to burn down everything they ever did.”
—Malcolm Bradbury (b. 1932)
