Discuss what is currently known about the role of sleep in memory formation.
What will be an ideal response?
Scientists are certain that sleep in general is important to memory processing. Sleep-related changes in memory might be different from the changes that occur when we learn something while awake. Learning during waking might be a simple matter of strengthening connections, whereas sleep-related memory processes might involve the reorganization of existing memory systems to accommodate new information. The day's memories can be reactivated during NREM and redistributed from the hippocampal circuits to the cerebral cortex. Memories now stored in the cerebral cortex can then be strengthened during REM, which will make the memories easier to recall during waking. Sleep also plays a role in reconsolidating memories. When we reactivate, or retrieve a memory for use, such as remembering the name of a structure for your behavioral neuroscience midterm, the memory becomes "open" to modification. The memory must undergo reconsolidation to become stable once more. Even a relatively short (40-minute) period of sleep showed benefits for reconsolidating reactivated memories.
