How does our brain help us search for objects that we know is somewhere around but are not sure about the exact place? Scientists found that the brain activates specific regions to help with the search.
During such search missions, other regions of the brain involved in some other task get roped in for this job.
"Our results show that our brains are much more dynamic than previously thought, rapidly reallocating resources based on behavioural demands, and optimising our performance by increasing the precision with which we can perform relevant tasks," said Tolga Cukur, lead author of the study.
Researchers used functional magnetic resonance imaging (fMRI) to record brain activity as study subjects searched for people or cars.
More of the cortex got allocated when the search target was humans and when search target was vehicles; the cortex seemed to prioritize vehicles.
"These changes occur across many brain regions, not only those devoted to vision.In fact, the largest changes are seen in the prefrontal cortex, which is usually thought to be involved in abstract thought, long-term planning and other complex mental tasks."
