Adult brain, nervous system pathways were fixed and unmodifiable. (Ramony Cajal, 1928)
Researchers began to discover growth and reorganization of neurons in the adult CNS after injury.
Injury to the CNS
direct damage, impair cerebral blood flow,
control of the cerebrospinal fluid or metabolism
Diaschisis ->first event
Temporary disruption of function produced by the shock of damage to the brain tissue. (stein, 1995)
Use PET, researchers indicate that in many cases, with time the patient recovers to normal activity.
< measure blood flow to various parts of the brain >
Drugs such as Amphetamine may promote recovery of function.
PET= positron emission tomography(양전자 방출 단층촬영술)
