Saccade:
Jennifer Groh at Duke University in Durham, North Carolina, and her team have been using microphones inserted into people’s ears to study how their eardrums change during saccades – the movement that occurs when we shift visual focus from one place to another. You won’t notice it, but our eyes go through several saccades a second to take in our surroundings. [“Your eardrums move in sync with your eyes but we don’t know why,” Aylin Woodward, NewScientist (29 July 2017)]
An interesting article, although I wondered if they had the horse before the cart.
