Scientist Steven Wiederman from the University of Aukland (shown in image below) has recently published his work suggesting that dragonflies have the ability to focus on a target while blocking out other useless visual information. This is known as selective attention and his work is the first to demonstrate this ability in neurons from an invertebrate.
