Interestingly, here’s a study that proves that the ageing brain displays more bilateral communication than the young brain. A team of researchers from the Duke Department of Neurology, US, used transcranial magnetic stimulation (TMS), a brain stimulation technique, to modulate the brain activity of healthy elders while they performed a memory task. It was found that when activity in a memory region of one of the hemispheres suffered, communication with the same region in the other hemisphere was initiated. The study points out that as people grow older, they use both the right and left hemisphere of the brain instead of relying on one side to perform memory tasks. Published in Human Brain Mapping, the study also suggests that such increased communication between bilateral regions of the brain helps to compensate for negative aspects of ageing.
