What is aphasia
inability to use language
controlled by Broca’s and Wernicke’s area, connected by the arcuate fasiculus
A
Broca’s area
area 44+45
B
arcuate fasiculus
C
Wernike’s area
area 22
What will damage to the arcuate fasiculus cause?
conduction aphasia, where the individual can understand language and produce language, but will have difficulty repeating what they hear
What do the superior and inferior parietal lobules do?
association areas that integrate the sensory stimulus from the adjacent somatosensory cortex, visual cortex, and auditory cortex
What happens with damage to the superior/inferior parietal lobules?
Damage to the association areas causes different kinds of agnosias, or inability to recognize sensory inputs. Damage to the right parietal lobe can cause hemineglect, an inability to recognize structures or even the patient’s own body on the left side. If the damage is on the left side, it can lead to apraxia, an inability to initiate movement.
What happens with damage to the fusiform face area?
can cause prosopagnosia, or an inability to recognize faces
Fusiform face area
