Association AreasAssociation areas are places where integration occursPre-motor area
Organizes motor functions for skilled motor activities Walking and talking
Cerebral PalsyMay be caused by O2 deprivation during birth which damages motor and association areas (may cause paralysis, spasms, lack of motor control)
Processing CentersProcessing centers of the cortex receive
information from the other association areas and perform higher-level analytical functions. Wernicke’s Area: understand written and
spoken language Broca’s Area: speech muscle control
