Why do some memories feel like we are actually reliving them?

What Makes a Memory Come Alive? - with Jon Simons · 50:15 · Video: The Royal Institution · Watch at the source

In short: While we understand how the brain recalls lists of words, the science of why certain memories feel vivid and multisensory remains a mystery. Cognitive neuroscientist Jon Simons explores the neural mechanisms behind the subjective experience of remembering.

Vivid memory involves more than just data retrieval; it requires the reactivation of sensory features, thoughts, and emotions to create a conscious, first-person experience. This process is vital for identity and allows us to distinguish between actual personal encounters and things we have merely imagined or heard.

Jon Simons, a reader in Cognitive Neuroscience at Cambridge University, examines how brain regions like the frontal, medial temporal, and parietal lobes contribute to this phenomenon. His research utilizes tools such as fMRI, EEG/MEG, and brain stimulation to investigate the gap between simple recall and the feeling of reliving a moment.
