learn by doing Although some brain structures are particularly important in memory, this does not mean that all memories
are stored in one place. The American psychologist Karl Lashley  attempted to determine where memories
were stored in the brain by teaching rats how to run mazes, and then lesioning different brain structures to
see if they were still able to complete the maze. This idea seemed straightforward, and Lashley expected to
find that memory was stored in certain parts of the brain. But he discovered that no matter where he
removed brain tissue, the rats retained at least some memory of the maze, leading him to conclude that
memory isn’t located in a single place in the brain, but rather is distributed around it.
