Summary of “When Your Eyes Move, So Do Your Eardrums”

Keep flicking your eyes back and forth, left and right.
As your eyes flitted right, both eardrums bulged to the left, one inward and one outward.
These wobbles happen every time you move your eyes, whether or not there’s external noise.
Groh has long been interested in how the brain connects information from our eyes and ears.
That’s easier said than done, because our ears are obviously fixed on our heads but our eyes are constantly moving.
They also found that the eardrums start to wobble about 10 milliseconds before the eyes.
Instead, Groh says, “The brain is saying: I am about to move the eyes; ears, get ready.”
Still, it’s clear that something is happening to the ears, and it’s intimately connected to what the eyes are doing.
