<P> Other significant evidence was produced in the 1960s and after, notably from scientists including Paul Bach - y - Rita, Michael Merzenich along with Jon Kaas, as well as several others . </P> <P> In the 1960s, Paul Bach - y - Rita invented a device that was tested on a small number of people, and involved a person sitting in a chair, in which were embedded nubs that were made to vibrate in ways that translated images received in a camera, allowing a form of vision via (sensory substitution)). </P> <P> Studies in people recovering from stroke also provided support for neuroplasticity, as regions of the brain remained healthy could sometimes take over, at least in part, functions that had been destroyed; Shepherd Ivory Franz did work in this area . </P> <P> Eleanor Maguire documented changes in hippocampal structure associated with acquiring the knowledge of London's layout in local taxi drivers . A redistribution of grey matter was indicated in London Taxi Drivers compared to controls . This work on hippocampal plasticity not only interested scientists, but also engaged the public and media worldwide . </P>

When does the brain have the most plasticity
