Diaschisis

Diaschisis (Greek for 'completely shocked', 'broken apart') is a (mostly sudden) loss of function in a part of the brain that lies outside the actually damaged area and thus a strict localization of damaged hierarchically higher (inhibitory) or hierarchically lower ( excitatory) areas of the CNS seems to contradict. The term goes back to the Russian-Swiss neurologist Constantin von Monakow (1853–1930), who coined it at the beginning of the 20th century. Neurons
move from the location of the originally damaged area to the location of the diaschisis. In the case of damage, either excitatory tracts (Monakov's original concept) or inhibitory tracts are omitted , which then causes the loss of function in the area affected by the diaschisis.
