• Damage to left frontal lobe (Broca's area)
• Expressive or productive aphasia - language problem, cant produce language in a fluid way, slow or belabored speech, difficulty writing as well
• Can understand others
• Can curse and sing because those are done in the right hemisphere 
• Theory: Broca's area stores the articulation codes that turn words into muscle actions necessary to produce them

• Damage to left temporal lobe (Wernicke's area) near auditory cortex
• Receptive aphasia - cant understand language 
• Speech is fluent but it doesnt make any sense
• Very hard to detect
• Cant understand themselves or others
• Theory: Wernicke's area converts sensory anaylasis performed by auditory cortex into meaningful words 

The process of the right and left hemispheres specializing for particulr functions. Babies can recover from aphasias because their brains can lateralize. 

Women are not as lateralized and therefore able to handle aphasias better if there is a tumor on the left side, she loses language on the right side however.

One "bad apple" can spoil the "barrel"

Strategy: limit information to one hemisphere and see how the information is processed

Right hemisphere specializations

• Spatial relations - facial recognition 
• Emotional tone 
• Prosody (patterns of rythm and sound)
• Yonal memory

• Analytical
• Language comphrehention 
• Academic 
• Logical
