How does the brain form memories and where are they stored?
We do not know for sure how the brain forms a memory. We do know that there are certain measurable changes in the brain that occur when something is learned. Some of these take the form of changes in connections between brain cells (neurons), making it easier for them to communicate with each other. We also do not know for sure where memories are stored. However, different parts of the brain seem to specialize in different forms of information: visual information is processed near the back of the brain, in the visual cortex, sensory information is processed in the sensory cortex, near the top of the head, and so on. However, in general, memories appears to be spread or “distributed” throughout large regions of the brain, rather than localized in any one place.
