What does A stand for in Lichtheim's house?

• A. Auditory representation (Wernicke's aphasia)
• B. Motor representations (Broca's aphasia)
• C. Conceptual area (ability to comprehend meaning)
• D. Visual representation

Answer: (A)

The main idea is how language processing is organized in Lichtheim’s house, with A representing the auditory representations—the stored phonological forms of words used when you hear speech or try to repeat it. This auditory image linkage is what Wernicke’s area handles, so damage to this system leads to fluent but often meaningless speech with poor comprehension (Wernicke’s aphasia). The other rooms map to different language functions: motor representations correspond to speech production (Broca’s area), the conceptual area to semantics and understanding of meaning, and visual representations to reading and written language. So A specifically stands for auditory representations.
