The Neuroscience of Memory

Our memories are our lives, and a fundamental basis of our culture. Collective memoirs of the past both bind society together and shape our potential future. With our brains we can travel through time and space, calling to mind places of significance, evoking images and emotions of past experiences. It’s no wonder, then, that we so desperately fear the prospect of memory loss.

Many regions of the brain are involved in memory, but one of the most critical components is the hippocampus, which plays a crucial role in the formation of long-term memories. Damage to the hippocampus can therefore result in significant memory loss. In this video, Eleanor Maguire draws on evidence from virtual reality, brain imaging and studies of amnesia to show that the consequences of hippocampal damage are even more far-reaching than suspected, robbing us of our past, our imagination and altering our perception of the world. Maguire also explains how, despite our beliefs, our memories are not actually as accurate as you might think. In fact, they’re not really even about the past.
