  • PNAS paper: 'Patients with hippocampal amnesia cannot imagine new experiences'
  • UCL memory and space research
  • UCL research into the relationship between amnesia and imagination is one of the top ten breakthroughs of 2007, according to 'Science' magazine.

    In January 2007, a team led by Dr Eleanor Maguire (UCL Institute of Neurology) reported in the journal 'PNAS' that people with amnesia caused by damage to the hippocampus, a part of the brain integral to memory, are also impeded in their ability to imagine future scenarios in detail, such as a shopping trip or a day at the beach.

    In particular, the researchers found that these limited imaginings lacked spatial coherence; the scenes the patients described involved few details, sounds and smells, suggesting that they were seeing fragmented images in their mind's eye rather than a holistic representation of each setting. On this basis, the academics suggested that the hippocampus may make a critical contribution to the creation of new experiences, by providing the spatial context that binds the disparate elements of an experience.
