Cortical neurons are tightly linked over long distances. It is estimated that the entire length of the linkages between the neurons within a single cubic millimetre of grey matter would cover about three kilometres. Every cell thus receives numerous thousands of input signals and transmits just as many output signals to, in part, distant neurons. This leads to a rapid wave-like distribution of excitations. What, however, happens if some of the normal input signals are suddenly no longer present due to the lesion of a sensory organ?
