Language

Question 1

what is brocas area?

Answer 1

Broca’s area(left frontal lobe) – speech production. As the motor region of language, it coordinates movement of the lips, tongue and vocal cords so that speech is possible. The use of grammar is also affected by Broca’s area. People with damage to Broca’s area (Broca’s aphasia) have difficulty getting words out, may stutter, and not construct grammatically complete spoken sentences.

Question 2

what is wernickes area

Answer 2

Wernicke’s area(left temporal lobe) – speech comprehension. People with damage to Wernicke’s area (Wernicke’s aphasia) struggle to understand others’ speech, and can speak fluent unbroken sentences but don’t make sense (a ‘word salad’).

Question 3

what is Geschwind’s territory

Answer 3

Geschwind’s territory(parietal lobe) – processing all aspects of speech (sound, meaning, visual written shape, etc.). It connects Broca’s and Wernicke’s area via a bundle of nerve fibres.
