The occipital lobes are found at the back of the brain, and they play a key role in how we see things. They make up about 30% of the brain's outer layer, called the cerebral cortex, and they help us understand the visual information that our eyes send through the optic nerve.
Here are some important points to know:
Primary Visual Cortex (V1): This part is the first stop for processing what we see. It takes up about 25% of the occipital lobe's area.
Visual Pathway: Information travels in steps from V1 to other areas called V2, V3, V4, and V5. Each of these areas works on different parts of sight, like color, movement, and how far away things are.
Fun Fact: About 90% of what our brain does involves visual information, showing just how important the occipital lobes are.
What happens if there's damage?
If this area gets hurt, it can cause problems with our vision, a condition called hemianopia. This happens to about 10% of people who have had a stroke.
The occipital lobes are also important because they help connect what we see with how we think and understand things. This shows just how crucial they are for seeing and interpreting the world around us.
