What does aphasia mean?
Without speech
When a person hears a sentence, which part of the temporal lobe is it transmitted to?
The primary auditory cortex
Which area then decodes the language into meaning?
Wernicke’s area
Which part is it transmitted to, if the sentence require a reply?
Broca’s area
Which part recognizes and names objects?
Left angular gyrus
Where is visual input transmitted to?
Visual cortex
Where are the objects recognized and named?
At the Left Angular Gyrus
Where is Wernicke’s area located?
At area 22 on the left hemisphere
Where is Broca’s area?
Brodmann areas 44 and 15
What does brodmann area 22 of Broca’s area produce?
The language production
What does brodmann’s area 45 of Broca’s area produce?
Grammatical structure
What does a lesion in Wernicke’s area result in?
Difficulty in understanding both spoken and written language
What does a lesion in Broca’s area result in?
Slow speech, and use of single words rather than sentences
What does damage to the angular gyrus lead to?
Alexia, that being the inability to read
