Why does Broca's aphasia and Wernicke's aphasia represent a double dissociation in cognitive neuroscience after a stroke?

💡 Explanation

The distinct functions of language production and comprehension are selectively impaired because Broca's and Wernicke's areas are damaged respectively, therefore demonstrating a double dissociation. This means that damage to one area impairs one function while leaving the other intact, rather than both areas being damaged and affecting both functions equally.
