Imagination as a Fundamental Function of the Hippocampus
because imagination depends largely, if not exclusively, on memory
there is absolutely no way you can imagine anything without the past
combining bits and pieces of experience with emotions, inner commentary and things people have read or heard about
Memory is a form of imagination
From an evolutionary perspective, we are reasonably sure that the purpose of memories is actually in the future
Memories allow you to take experiences that you have and retrieve them to make predictions about what will happen next
We also need to form memories of our simulations of the future so that when we have an experience, we have something to draw on
We have found that the encoding of an imagined simulation also involves the hippocampus
The firing patterns of place cells repeat about eight times per second in rats, forming what is called the theta rhythm
the place it just was, its current position and, late in the cycle, a possible upcoming location.
H M. lacked a sea-horse-shaped brain structure called the hippocampus and had amnesia. His case helped establish the hippocampus as an engine of memory
