Your brain has two halves:


  • Left hemisphere (usually handles language, logic, and speech)
  • Right hemisphere (handles spatial awareness, faces, emotions, etc.)

These two halves normally communicate through a bundle of nerves called the corpus callosum.

✂️ The Experiment​


In some epilepsy patients, doctors surgically cut the corpus callosum to stop seizures from spreading. These people were otherwise fine—but now the two sides of their brain couldn't talk to each other.

🧪 What They Did​


Researchers (like Roger Sperry and Michael Gazzaniga) showed different images to each side of the brain:


  • Example: Show the word “KEY” to the left eye (right brain), and “RING” to the right eye (left brain).
  • Ask the person what they saw: they say “RING” (because speech is in the left brain)
  • But ask them to point to what they saw with their left hand (right brain control), they point to a key.

So—each side of the brain had a different experience, but only the left could talk about it.
