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

vidual differences in people's visual tracking abilities. Some people, for instance, have trouble picking up a moving vehicle seen in a rearview mirror once it enters a blind spot. "This new technique allows us to watch the brain as information about a target is handed off from one side to the other, and it may provide insights into why attention is so limited," Vogel said.

While psychological studies have often looked at attention and awareness, there has been little focus on how the two hemispheres interact. Interestingly, Vogel said, cellphone companies have long studied a similar problem: how to best transfer a call's signal while a customer moves from one zone of a cell tower to another.

Cellular carriers using Code Division Multiple Access (CDMA) such as Sprint and Verizon utilize a soft handoff between towers, similar to the new findings. Global System for Mobile (GSM) carriers, such as T-Mobile and ATT, use a hard handoff in which a signal leaving a tower's coverage is rapidly shut off and then turned on by the next tower -- a scenario that tended to, before the technology improved, result in more dropped calls.
