Jonah Lehrer, in Proust was a Neuroscientist, suggests that Marcel Proust, in his
writing, predicted the, “instability and inaccuracy of [long-term] memory…” [1]. Before
the dawn of the 21st century, neuroscience suggested that memory, valuable pieces of
information, were archived in a structure in the brain, such as the lateral and basal nuclei
of the amygdala. In 2000, research on rats with fear conditioning and a protein inhibitor
showed that the act of remembrance (reactivation) in fact changed the molecular
underpinnings of the memory by making the memory ‘labile’ once again [2]. Therefore,
new protein synthesis at the synapse was needed to ‘reconsolidate’ the information to
