| Optical Illusions |
| This picture is an illusion that plays with your stereoscopic synthesis. The |
| dots appears to flip between black and white. Other illusions play with |
| depth perception. The Penrose Steps are a type of illusion that tries to |
| build an impossible physical model in our cerebral cortex. The brain sees |
| perspective and depth perception cues, but the resulting shape could |
| never exist. |
| Hearing |
| Unlike sight, hearing is an absolute sense. Our ears capture and focus |
| sound down to the eardrum where a set of small hairs called cilia convert |
| it into electrical impulses. The impulses stimulate cells corresponding to |
| specific pitches. |
| We are born with perfect pitch, yet most of us lose it early on. When |
| I hear Maria Carey sing a top B flat a specific set of neurons located near |
| the ear fires, and if she sings a top 'A' then a different clump of neurons |
| are stimulated. By the time most children come to learn music they have |
| edited out this absolute pitch information. One group of children who |
| do not lose the ability are Chinese pianists. Because Chinese is a tonal |
| language - where the pitch of words affects their meaning - and because |
