Front 7

Broca's Aphasia (non-fluent aphasia):
-define
-damage of what area?

Back 7

Motor speech impairment. Limited vocabulary and slow, hesitant speech due to damage of Broca's area (Brodmanns 44) in the dominant hemisphere, typically the left.
"Expressive aphasia"

Front 8

Wernicke's Aphasia (fluent aphasia)
-define
-damage of what area?

Back 8

Receptive speech impairment with impaired auditory comprehension and fluent speech with normal rate and melody.
Due to damage of Wernicke's cortical area (Brodmann's 39,40) in the dominant hemisphere, typically the left.

Front 9

Global Aphasia
-define
-signs
damage to ...

Back 9

Expressive and Receptive aphasia
Non-fluent speech with poor comprehension
Due to damage of both the third frontal convolution and posterior portion of the superior temporal gyrus

Front 10

Perceptual Deficits

Back 10

Due to damage of the parietal sensory cortex in the nondominant hemisphere (usually the right)
