Ramón y Cajal 160th Birthday


Google, a company (once) known for it’s “Don’t be Evil” corporate motto, has a fun practice of regularly replacing its homepage logo with various doodles.

Earlier this month, exactly 160 years have passed since birth of Santiago Ramón y Cajal. Ramón y Cajal’s pioneering investigations of the microscopic structure of the brain made him the father of modern neuroscience. He was skilled at drawing, and hundreds of his illustrations of brain cells are still used for educational purposes today.

Google payed the respect to the Spanish pathologist, histologist, neuroscientist, and Nobel laureate with the following “optical illusion” doodle. If you can remember of some other memorable illusory doodles, Google used in the past, be sure to embed them in your comments!

    eh. it is pretty good but not amazing.

    another cool doodle is the robert moog 78 b-day. Rob created the synthesizer and thats what the doodle is. the knobs on the headboard spell good while the wires spell le and in all, it spells google. but thats not all. you could actually play the notes and press the knobs and stuff.really epic.

    hmmmm. Sorta an obvious illusion. Still cool.

  • Rahowa

    BOO! Not an illusion

  • Thomas

    You know it says GOOGLE too along with just the head.

  • Terry

    Is everyone missing that the branches of the brain also spell Google?

  • Cyphis

    I just wanted to point out that there are actually three illusions in this doodle since some people seemed to be dissapointed or think it’s obvious and simple.
    1, the “obvious” face in the center
    2, the spelling out of the word “Google”
    and 3, the “tree” that’s making up the whole piece is actually a brain.
    I’m hoping, once viewers acknowledge all of these features of the piece, they will appreciate it more.

  • kunga

    way too obvious. no chalange there

  • My Opinion


  • eee efff geee

    Not really an illusion, but I like it :)

  • Have it not been there before?
    Or is it just me?

  • Josue Boo

    So, there are two illusions: the obvious face and the hidden word “Google”. I liked the word more, of course.

  • suri

    The face is difficult to hide (and a bad piece of art)…. but the 2 monkeys on the branch are difficult to spot

  • Sakura

    Maybe the whole perspective of the face is to catch your attention instead of the word “Google” to make it more of an illusion. :)

  • why me!?!?

    i didn’t notice the word Google until i read the description! EPIC!

  • aNN

    not much of an illusion. Really obvious.


    There are many you have missed. 2 heads of dear above to his left. to right a hands and arms folded male. next to that is 3 smiling women. To his left is a large face and a blank one with ears. A granny on his shoulder and a bird to the right plus much more!

    • TOMMY

      YES; I see!

  • Nicholas Wade also created hidden portrait of Cajal somewhat similar to this Google logo as part of his Portraits of European Neuroscientists series.

    its a might fine illusion to me.
    If its “obvious” to you, you probably are a devoted fan of MO Illusions.
    Even if it is truly obvious, can we just appreciate the fact that it is an illusion-complex or not?
