Test your Brain and Mind with these 9 Classic Optical Illusions

Are the two orange circles of the same size? 

One way to learn more about our brains and minds is to look at how we can trick them–that is, to see how we react to brain teasers and visual illusions.

Quick facts: The brain has two hemispheres, each divided into four lobes. Each lobe is (largely) responsible for different functions. For instance the frontal cortex (in yellow) is responsible for decision making and planning; the temporal lobe (in purple) for language and memory; the parietal lobe (in green) for spatial skills, and the occipital lobe (in red) is entirely devoted to vision: It is thus the place where visual illusions happen..

Below are 9 optical illu­sions that com­bine fun and learn­ing about our visual system. We know you know there is a trick since these are illu­sions… but don’t try to be smarter than your brain; enjoy being surprised!

Test your memory and reasoning skills with these American and international proverbs

Temporal lobe Frontal LobeMemory relies mostly on temporal (see green area, in image to the left) and frontal (in red) areas of the brain. These may be the areas that will get stimulated when you (assuming you are American or have lived in the US for long) try to remember the missing words in the American proverbs below.

However when it comes to internationals proverbs below you may have to use your reasoning skills more than your memory skills, as it is likely that you do not know these proverbs.
