More evidence of brain plasticity: Some blind people are able to use echolocation to perceive space and objects around them in surprising detail, even though the time differences in echoes necessary to do this are two small to be consciously perceived. An fMRI study by Lore Thaler, Stephen Arnott and Melvyn Goodale revealed that people who are especially adept at this use their calcarine cortex (a.k.a. V1 or primary visual cortex) to process spatial information from the echoes.
