Eye Movements Indicate Coordination of Arms

New York University neuroscientists have discovered that humans make eye movements earlier or later in order to coordinate with the movements of their arms. Furthermore, the study points to a mechanism in the brain that allows for this coordination, and may have implications for rehabilitation and prosthetics. Research results appear in the journal Neuron.

Researchers sought out to understand the neurological processes behind eye and arm movements. For example, when you reach for an object, what goes on in our brains to cause your eyes and arms to sync? Such coordination is key to the way different brain systems communicate with each other. These undertakings are surprisingly complicated; due to differences in weight, for instance, the arm takes longer than the eye to move.  For more information, click here to read the full release.
