Mapping changes in taxi drivers’ brains

One of the most dramatic examples of neuroplasticity (the plasticity of our brain at work comes from a 2000 brain scan study on London taxi drivers (Maguire et al., 2000). In order to earn a license, London taxi drivers typically spend about two years learning to navigate the city’s serpentine streets. What mark, the study’s researchers wondered, did this long, rigorous period of training leave on taxi drivers’ brains? Under the scrutiny of fMRI scans, 16 male taxi drivers were revealed to have larger hippocampuses than a control group of 50 healthy males. And the longer the time spent as a taxi driver, the larger the hippocampus tended to be. As a brain area involved in memory and navigation, the hippocampus seemed to have changed in response to the taxi drivers’ experiences.
