The Neuroscience of Illusions and Dictionaries
Scientific American is running a pair of stories about what words and illusions can tell us about the brain. Mark Changizi of the Rensselaer Polytechnic Institute is interviewed about his research into the relationship between the mechanisms of the brain and the evolution of language. The second article contains a slide-show of various illusions and why the brain interprets them as it does.
American Scientist ran an article about Light traps for light processing, Tip-of-the-Tongue processing states of memory and speech creation, Parkinson's Disease discussion, and a Moon surface discussion.
And Scientific American (spit) runs yet another optical illusion article. I knew there was a reason why we dumped them and went AmSci.
