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!

Better Optical Illusions

illusion-d'optiqueOptical illusions are fascinating in many ways—they can create objects that cannot exist, movement in a static image, different colours with the same colour, and so on. They can also give us a better understanding of how the human visual system works, as witness this web site dedicated to the best optical illusions that scientists who study this subject have managed to devise in a contest that is held every year.

The example above took first prize in the 2007 contest and actually consists of two identical photos of the Leaning Tower of Pisa, placed side-by-side. But our visual system insists on seeing them as a single picture of two towers, which gives us the impression that the tower on the right is leaning more than the one on the left.

    Sorry but I have to agree with the comment that you don’t rlaley know what TRUE brain fog is. I have Lyme Disease and I can tell you that all your little suggestions have no impact on TRUE brain fog. Of course eating better will help to some degree but will not eradicate TRUE brain fog. The condition you speak of is a rather vague way of describing a feeling that most people get on occasion and is transient. TRUE brain fog is 24/7, 365 and feels like your brain is on novocane.
