1. Carl Wernicke proposed that an area in the left temporal lobe, now known as Wernicke's area, is responsible for language comprehension and processing based on his observations of patients with left temporal lobe damage. 2. Wernicke's area is located at the junction of the parietal, temporal, and occipital lobes in the left hemisphere and is involved in language comprehension, semantic processing, language recognition, and interpretation. 3. The Wernicke-Geschwind model expanded on Wernicke's findings and proposes pathways for hearing, speaking, reading, and their relationships to brain areas including Wernicke's area and Broca's area.
