Taxi case study: Maguire (2000)

Storyboard Text

  • Maguire studies London Taxi drivers to see if their brains are different as a result of their exceptional knowledge of the city and the many hours that they spend behind the wheel navigating the streets of London.
  • She does this to see how cognitive processes may lead to neuroplasticity in the hippocampus
  • 16 male right handed Taxi drivers take a knowledge test and must have 1.5 years of experience to be a part of this experiment
  • 50 right handed men who do not drive taxi's are a part of this experiment as well.
  • Brains from both groups are scanned to be compared
  • - The Data from the MRI scans were measures using pixel counting and Voxel-Based Morphology- Pixel counting showed that the posterior Hippocampus of the Taxi driver's grew in size, while the VBM showed that there was an increase in density of matter in the brain of the Taxi drivers.
  • Taxi Driver's MRI
  • Average man's MRI
  • - Maguire argues that this demonstrates that the hippocampus may change in response to environmental demands.- The posterior hippocampus is involved when previously learned spatial information is used
