In your mind's eye

I love the way the mind works. I spent years studying cognitive psychology, which was my college major (I was the psych geek who paid you $3 to sit in front of a computer for 10 minutes and take a test where what I told you I was testing for was not what I was testing for . . . ).

My dad sent me the following link, which is pretty fun.

A great example of neuronal accommodation. This is clearly happening in primary visual cortex (V1) because it's extremely sensitive to your fixation (i.e., if you move your eyes even slightly, some of the pink dots reappear).

There are theories that this is why we saccade ... if you look at one spot too long, everything disappears.
