From Wikipedia, the free encyclopedia

1968 is too old

Can we get an updated source to cover the facts sourced to old papers? Biosthmors ( talk) 00:24, 21 November 2012 (UTC) reply

I'm not sure the new lead is an improvement. I restored the old version. Biosthmors ( talk) 00:27, 21 November 2012 (UTC) reply

This article needs improvement

I want to bring attention to the need for general editing of this article to improve the reading quality. I hope to slowly improve the sentence structure here and there when I am able. Jayhvvip ( talk) 22:54, 13 November 2013 (UTC) reply

Shouldn't this article be merged with Area postrema?
