One of my old science teachers in 2nd grade said that on her first day.

"You get a new wrinkle each time you learn something. At the end of the year you will all have very wrinkly brains."

Is there any research into this? Anything proven?

No, it’s not true. Your brain is pretty much the same shape as when you were born, it just gets a little bigger as you grow up.

The surface of the brain is where the cell bodies are, so the bigger surface area there is, the more cells. Human brains are wrinklier (generally speaking) than animal brains for this reason. However, cells are so tiny that gaining or losing several thousand isn’t going to change the shape of your brain at all.

I hate it when teachers make stuff up just to sound cute…some people don’t seem to realize that little kids are very literal-minded!

    definitely not.the brain grows to its full size at the age of 5-6yrs and the number of wrinkles are fixed and r determined by heredity.

    No way. Perhaps a few new neurons in your hippocampus, at most.
