Equipotentiality hypothesis is given by Karl Spence Lashley who discovered that brain has the capacity to transfer functional memory from injured part to the undamaged portion in case of injury. He furthermore suggested that the efficiency of brain to perform complex functions after injury depends on the extent of damage the whole brain has suffered, apart from the portion of injury. Hence, the storage capacity of brain is flexible and depends on the functioning capacity of undamaged parts of the brain after an event of injury.
