Detailed explanation-1: -Method: Structural MRI scans were obtained. 16 right-handed male London taxi drivers participated; all had been driving for more than 1.5 years. Scans of 50 healthy right-handed males who did not drive taxis were included for comparison.
Detailed explanation-2: -In her earliest studies, Maguire discovered that London taxi drivers had more gray matter in their posterior hippocampi than people who were similar in age, education and intelligence, but who did not drive taxis.
Detailed explanation-3: -The part of the brain that navigates spatial intelligence is called the hippocampus, a pair of two chestnut sized masses toward the back of your head. The researchers found that London cab drivers have uniquely bigger hippocampi than almost anyone else.
Detailed explanation-4: -Previous studies have shown that taxi drivers have a larger hippocampus compared to non-taxi drivers. This is interesting as this brain region shrinks and becomes damaged in Alzheimer’s disease, leading to symptoms of memory loss and confusion associated with the disease.
