Decussation — definition?
Crossing over of nerve fibers in the CNS.
Aphasia — stroke effect?
Language impairment due to brain damage.
Language vs Speech — difference?
Language is a symbolic system; speech is motor production.
Decussation — definition?
Crossing of nerve fibers between hemispheres.
Great Decussation — location?

Aphasia — cause?
Brain damage affecting language.
Decussation — role?
Enables contralateral movement control.
Stroke — effect?
Can cause aphasia or hemiparesis.
