Document Summary
Ability to modify, mold, or to assume a desired shape. Enables synaptic strengthening or weakening over time in response to increases or decreases of activity. Refers to interrel"t proceses: normal dev"l, learning, recovery from injury. Cerebral funct: innately specialized: localization of funct in cerebral cortex. Poor outcome after insult (early vuln: interactive specialized: compromise. Brain dev"l increases in specialization of responses of properties specific to brain regions; changes in interaction and competition to acquire roles. Compromise: equipotentiality (coined by lashley ): brain has the ability to use any functioning part of the brain to carry out a task that a dmg are can no longer do properly. Subject to law of mass action which state that the efficiency of any complex funct of the brain is reduced proportionate to how much dmg the brain as a whole sustained. Continuum model: early plas an vul as checkpoint along dev"l.
