After providing all the funding for The Brain from Top to Bottom for over 10 years, the CIHR Institute of Neurosciences, Mental Health and Addiction informed us that because of budget cuts, they were going to be forced to stop sponsoring us as of March 31st, 2013.

We have approached a number of organizations, all of which have recognized the value of our work. But we have not managed to find the funding we need. We must therefore ask our readers for donations so that we can continue updating and adding new content to The Brain from Top to Bottom web site and blog.

Please, rest assured that we are doing our utmost to continue our mission of providing the general public with the best possible information about the brain and neuroscience in the original spirit of the Internet: the desire to share information free of charge and with no adverstising.

Whether your support is moral, financial, or both, thank you from the bottom of our hearts!

The Impression of Déjà Vu.

This week we’d like to suggest some readings on a strange phenomenon that people may experience when travelling, among other occasions: the impression of déjà vu.

The first link below describes just one example of this phenomenon: you are touring a castle in a country that you are visiting for the first time, when suddenly you have the impression that you have been there before. But after the tour, while visiting the castle’s gift shop, you see a postcard with a photo of the castle, and you realize that a movie that you saw several years ago was shot there. The two experiences seemed too distant or disjointed in your memory for you to make the connection explicitly, but they were close enough for you to have an implicit sense of familiarity.

But that is only one of the many possible explanations for déjà vu. In fact, there are at least 40 different theories about this elusive phenomenon. They are not mutually exclusive, because déjà vu can probably be triggered by a variety of mechanisms. Three of these are explained in the short video that you can view at the second link below. The third link below is to an article that shows how different areas of the temporal lobe are activated when you experience the feeling of familiarity as opposed to when you actually recall a memory.
