Surface mapping of the results of a fibre tracking study in which the topology of the cortical connectivity network in early blind subjects was compared with that in normal controls. The nerve fibres being tracked are actually situated below the cortical surface, but the cell bodies of the neurons in these fibres are situated in the cortical grey matter, which exhibits regional functional specialization. Mapping the results on the cortical surface provides a convenient way for neuroscientists to put them into the perspective of related findings, which are often depicted as correlations between function and location. Blue: regions with decreases in both the degree of connectivity and the global efficiency and with an increased characteristic path length in the early blind; Red: regions with increased degree of connectivity and global efficiency in the early blind; Top: left brain hemisphere (LH); Bottom: right hemisphere (RH). Left: Lateral view; right: medial view.
