The occipital lobe is a part of the brain located at the back. Its main job is to help us process what we see. Here are some important details about it:

1. Primary Visual Cortex (V1):

   • This area gets signals from our eyes through the thalamus.
   • About 30% of our brain is used for seeing things.

2. Visual Pathways:

   • Dorsal stream (where): This pathway helps us see motion and understand where things are.
   • Ventral stream (what): This pathway helps us recognize objects and understand their shapes.

3. Statistical Facts:

   • More than half of the sensors in our body help us see.
   • If the occipital lobe gets hurt, it can lead to a condition called cortical blindness, which can take away up to 90% of our ability to see.
