     Summary:   
         Researchers have found that the ability to visually predict movement   
         may be an important part of the ability to make a great catch --   
         or grab a moving object.

   FULL STORY   
   ==========================================================================   
   Have you ever made a great catch -- like saving a phone from dropping into   
   a toilet or catching an indoor cat from running outside? Those skills --   
   the ability to grab a moving object -- takes precise interactions within   
   and between our visual and motor systems. Researchers at the Del Monte   
   Institute for Neuroscience at the University of Rochester have found   
   that the ability to visually predict movement may be an important part   
   of the ability to make a great catch -- or grab a moving object.   
      
   "We were able to develop a method that allowed us to analyze behaviors in   
   a natural environment with high precision, which is important because, as   
   we showed, behavioral patterns differ in a controlled setting," said Kuan   
   Hong Wang, PhD, a Dean's Professor of Neuroscience at the University of   
   Rochester Medical Center. Wang led the study out today in Current Biology   
   in collaboration with Jude Mitchell, PhD, assistant professor of Brain   
   and Cognitive Sciences at the University of Rochester, and Luke Shaw,   
   a graduate student in the Neuroscience Graduate Program at the School of   
   Medicine & Dentistry at the University of Rochester. "Understanding how   
   natural behaviors work will give us better insight into what is going   
   awry in an array of neurological disorders."  Researchers used multiple   
   high-speed cameras and DeepLabCut -- an AI method that uses video data   
   to find key points on the hand and arm to measure movements -- to record   
   where the primate is looking and the movement of the arm and hand as it   
   reaches and catches moving crickets. Researchers found an 80- millisecond   
   delay in the animal's visuomotor behavior -- the moment when vision and   
   movement click and work together to direct the hand toward the target.   
      
   Despite this measurable delay, the primates still grabbed the crickets,   
   meaning that they had to predict the cricket's movement. Using data of   
   both the primates and the crickets the researchers were able to build   
   a detailed model of vision guided reaching behavior.   
      
   "These findings allow us to identify unique behavioral control   
   strategies for mechanistic studies and engineering applications,"   
   said Wang. "Visuomotor control problems exist in many neurological   
   disorders due to brain lesions, stroke, and genetic factors. This   
   research may help develop computational behavior analysis strategies to   
   precisely characterize behavioral alterations in naturalistic settings   
   and understand their underlying causes."  This work was supported by   
   the National Institute of Health, the Schmitt Program of Integrative   
   Neuroscience, and the Del Monte Institute for Neuroscience Pilot Program.
