In their investigation of neuroplasticity, Maguire et al. (2000) compared the structural MRI scans of London taxi drivers with those of matched control participants.
Which of the following statements accurately summarizes the structural differences observed in the hippocampus and their relationship to taxi-driving experience?
Control participants demonstrated significantly greater grey matter volume in the posterior hippocampi compared to taxi drivers, which correlated negatively with taxi drivers' years of experience.
Taxi drivers demonstrated a redistribution of grey matter, showing significantly greater volume in the posterior hippocampi compared to controls, which correlated positively with time spent taxi-driving.
Taxi drivers demonstrated significantly greater grey matter volume in the anterior hippocampi compared to controls, which correlated positively with time spent taxi-driving.
Taxi drivers demonstrated an overall increase in total hippocampal volume compared to controls, with both the anterior and posterior regions showing a strong positive correlation with driving experience.
