WOODS HOLE, MASS.--Paloma T. Gonzalez-Bellido, who is now a postdoctoral scientist at the Marine Biological Laboratory (MBL), and colleagues from Howard Hughes Medical Institute, University of Minnesota, and Union College have been awarded a 2012 Cozzarelli Prize by the editorial board of Proceedings of the National Academy of Sciences (PNAS).
Gonzalez-Bellido and colleagues were honored for the "scientific excellence and originality" of their study of prey detection and interception in dragonflies.
The research was performed at Howard Hughes Medical Institute's Janelia Farm Research Campus, where Gonzalez-Bellido was a postdoctoral scientist prior to joining the MBL's Program in Sensory Physiology and Behavior in September 2011.
The study provides insight into basic visual-motor neural processing, and has implications for the development of "bioinspired" prosthetics for humans.
"I am honored to receive recognition for this work, for which we bridged the clinical and neuroethological fields, and developed new techniques," says Gonzalez-Bellido. "This award has provided me with fuel to keep up the hard work and further my research plans."
In order for a dragonfly to intercept its prey in midair (which dragonflies do with a 95% success rate), it needs to quickly track the prey and predict its future location. To understand how they undertake this complex task, Gonzalez-Bellido and her co-authors studied a small group of 16 motor neurons, called target-selective descending neurons (TSDNs), in the dragonfly Libellula luctuosa. These neurons, originally discovered by co-author Robert M. Olberg (Union College) in the green darner dragonfly, originate in the brain and extend to the thoracic ganglia, where the neural signal is interpreted and translated into wing muscle movements. Surprisingly, the scientists found that this small group of neurons can detect the direction of target prey with high accuracy and
