The occipital lobe
Occipital lobe · lobus occipitalis
The back of your brain, where seeing actually happens.
What it does
The occipital lobe at the back of the brain receives signals from the eyes and turns them into vision. Separate areas handle edges, colour, motion and shape before passing the picture forward to be recognised. Each side processes the opposite half of what you see.
Surprising fact
You see with the back of your head: the eyes are at the front, but vision is processed about as far from them as the brain allows.
Why it matters
A hard knock to the back of the head can make you "see stars", because it jolts the visual cortex, and strokes here can cause loss of half the field of vision in both eyes.
