  • How long do we keep what was perceived by the retina in memory? (how many frames?)
  • How long do we keep what was perceived by the cochlea in memory?

  • We should expect to be limited by the maximal rate of neuron firing, but is it possible to communicate information faster?

Part of the brain continues to process images for longer than 13 milliseconds to respond positively after a sequence of rapid-fire pictures 1

  • We have the ability to access our memory at will
  • The memory seems to be accessible in many ways and indexed through different means
  • Maybe it is available in a graph form such that thinking in time period uses a region where indexing is done in that manner
  • Some memories may be directly accessed if we aren't querying something of particular interest
  • However, if we want to remember something more specifically, then we may enter a form of filtering where we query by asking for appropriate indexes
    • e.g., what was I doing in 2007 at school?
