Brain Multitasking

An inability to deal with more than two things at a time may be "hard-wired" into our brain, research suggests.
When we try to do two things at once, each half of the brain focuses on a separate task, French scientists say.
It might also explain why people are prone to make irrational decisions when choosing from a long list of items.
Lead author Dr Etienne Koechlin told the BBC: "You can cook and at the same time talk on the phone but you cannot really do a third task such as trying to read a newspaper. If you have three or more tasks you lose track of one task."
When the volunteers completed one task at a time, one side of a certain area of the frontal lobes lit up.
But, when they completed two tasks at the same time, the lobes divided the tasks between them.
The brain was able to control switching between the two hemispheres when carrying out dual functions but accuracy suffered when a third was added.
