Smooth brain

In recent studies on the media dominating instant messaging platforms like Instagram, I have came to the conclusion that the media can have a negative effect on youth. The media is feeding these youth groups information that results in degrading of the brain. I dub this effect the “smooth brain” effect.

Smooth Brain

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.

smooth-brained

An insult referring to the absence of wrinkles present in the human telencephalon(cerebrum) -- the largest region of the mammalian brain. Literally implying idiocy at a physiological level.

Smooth Brain

Opposite of big brain. Smooth brain refers to an idiot or someone dumb. Neuroscientists believe the more folds you have in your brain means the smarter you are. Therefore if you are called smooth brain, you have less folds and therefore dumb.
