Interpretation of Wernicke's area in action
Understanding spoken language:
Primary auditory cortex (41/42) -> Wernicke's A. (22) -> semantic networks distributed throughout the brain.
Spontaneous speech: "cognitive" areas send input to Wernicke's area:
Cognition -> Wernicke's A. (22) -> arcuate fasciculus -> Broca's A. (44)-> Primary motor cortex
