Neuroplasticity is useful for brain damages and treatment for traumatic injuries and strokes.

The control group consisted of MRI scans from 50 right-handed males aged 32-62yrs. The taxi drivers brain was scanned using an MRI scanner. An MRI scan shows the structure of a brain without having to undergo surgery. The scans were then observed and compared to the control group's scans. They were observed in two ways; firstly through Vortex Based Morphometry (VBM), which measures the volume of Grey Matter in the brain and then pixel counting; which measures the size of the amount of grey matter in the brain. The pixel counting was carried out by a blind person to avoid bias. Overall, the VBM shows there was an increase in the amount of grey matter in the brains of the taxi drivers, whereas the pixel counting showed no difference in the size of the hippocampus however the...
