Oregon researchers capture handoff of tracked object between brain hemispheres
Date:5/8/2014

EUGENE, Ore. -- When tracking a moving object, the two halves of the human brain operate much like runners successfully passing a baton during a relay race, says a University of Oregon researcher.

In a study online ahead of print in Current Biology, electroencephalogram (EEG) measured brainwaves from healthy young adults revealed how information about an attended object -- one being watched closely -- moves from one brain hemisphere to the other.

Such handoffs are necessary because the human visual system is contralateral; objects on the left side of space are processed by the right hemisphere and vice versa. When objects change sides, the two hemispheres must coordinate so that the tracked object isn't lost during the exchange.

"Attentional tracking is something we do on a regular basis when driving in traffic or walking through a crowd," said Edward K. Vogel, professor of psychology. "Our world is dynamic. We're moving. Our eyes are moving. Objects are moving. We need to use our attention to follow objects of interest as they move so that we can predict where they are going."

People experience a smooth and seamless visual world despite information quickly being transferred back and forth between the hemispheres. "A car in your rearview mirror that moves from one lane to the other doesn't suddenly disappear and then reappear on the other side," he said. "The exchange is smooth, in part, because often the hemispheres coordinate a soft handoff."

That means, he said, that before the object crosses into the other side of space, the new hemisphere picks it up, and the old hemisphere continues to hang on to it until it crosses well into the other side of space. Both hemispheres grab hold of the object during the exchange -- much like in a relay race when two runners both briefly have hold of the baton to assure it isn't dropped.

Eventually, Vogel said, such research may help us better understand indi
