Where could representations be stored in an animal?

• A. Brain, long-term or short-term memory
• B. Spinal cord
• C. Muscle memory
• D. Liver

Answer: (A)

Representations are stored in neural tissue within the brain. Short-term or working memory lives in frontal–parietal circuits, keeping information active for brief periods to guide current tasks. Long-term memory involves the hippocampus for consolidation and distributed cortical areas where the actual representations are stored as patterns of synaptic connections. Motor learning also maps to brain networks, such as the motor cortex, basal ganglia, and cerebellum. The spinal cord mainly relays information and supports certain learned reflex pathways, but it doesn’t host the broad representations of memories. The liver stores metabolic substrates, not memories. So, the brain—encompassing both short-term and long-term memory stores—is the place where representations are stored.
