  • How exactly does a brain store information?
  • How are our memories first formed?
  • What makes us forget them, or create false
  • or distorted memories?
  • What happens in dementia or neurodegeneration, when our memories crumble?
  • Looking to the future, how might we keep our memories intact, as our lifespans extend?
  • What will be the impact of AI?


Written by a professional quizzer and neuroscientist Hold That Thought is a concise, accessible and entertaining guide to all aspects of our memory. Drawing on personal experience and historical case studies, Darragh Ennis touches on subjects as wide-ranging and fascinating as plant and animal memory, our memory’s relationship with taste, smell and sleep, and how we might strengthen our memories to competitive level.

Did you know?:

  • Short term memory is only a few seconds.
  • Memories exist as physical objects in your brain. Any long-term memory is stored in a trace of neurons in a particular pattern.
  • Photographic memory doesn’t really exist.
  • Goldfish memories are actually pretty good, they are unfairly maligned!

Critics' reviews

Brilliant, compulsory reading. In Hold That Thought, Darragh perfects the art of writing entertaining, jargon-free explanations of complex and relevant science, while retaining scientific accuracy and integrity gained during our joint research in Oxford on fly neuroscience.
