A few days ago, I briefly discussed the article by Oliver Sacks about geometric hallucinations in migraine aura. I thought that it was published in the print edition of the *New York Times*, but it turns out that this is in fact Sacks's first post on a new *NY Times* blog called Migraine: Perspectives on a Headache.

Sacks is one of five "migraneur" contributors to the new blog. (His co-bloggers are author Siri Hustvedt, journalist Paula Kamen, neurologist and psychiatrist Klaus Podoll and musician Jeff Tweedy.) The post/article about visual migraines generated a lot of discussion, and, in his second post, Sacks answers some readers' questions. Also of interest is Huvstedt's recent post about Alice in Wonderland syndrome.

Sacks is the author of 10 books including the classic *The Man Who Mistook His Wife For A Hat* (1985), which is a collection of essays describing people with bizarre neurological syndromes. He is a fantastic science writer, so it's great to see him blogging. The blog he is contributing to will be of particular interest to migraine sufferers, but also to others.
