Which brain network is commonly active for both memory and imagination?

• A. Default network
• B. Salience network
• C. Executive network
• D. Visual network

Answer: (A)

The question taps into which brain network underlies internally generated thought like remembering the past and imagining the future. The default mode network is most active during memory recall and when you simulate possible scenarios, integrating memory stores with ongoing mental construction to create coherent scenes. It links memory-related regions, such as the hippocampus, with cortical areas to support both retrieving experiences and envisioning them in detail. This network’s activity reflects how the brain readily turns inward to reflect, plan, and imagine, rather than focusing on external tasks. The salience network is more about detecting important stimuli and helping switch between networks, the executive network handles cognitive control and problem-solving, and the visual network processes present visual input. So the default mode network best explains why both memory and imagination light up the same large-scale system.
