A critique of successor representations as a model of learning in the hippocampus

Artificial General Ideas • 1 implied HN point • 14 Sep 24
🔬 Science Neuroscience
  1. Successor representations (SR) does not explain how place cells in the hippocampus learn or form. It assumes inputs that are already perfect place fields, so it can't help in understanding their development.
  2. Many claims about SR's abilities, like making predictions or forming hierarchies, actually relate to simpler models like Markov chains. SR doesn't add much value to those features.
  3. Experiments often used to support SR in humans might actually show evidence for more general planning methods. Model-based reasoning seems to fit the observed behavior better than SR does.

Space is a sensory-motor sequence in the hippocampus

Artificial General Ideas • 1 implied HN point • 12 Aug 24
🔬 Science Neuroscience
  1. The hippocampus may not just represent physical space but instead processes space as a sequence of sensory and motor experiences. This means how we perceive space comes from our interactions, not just where we are.
  2. Place cells in the brain react to specific sequences of observations rather than directly to locations themselves. This explains why experiences in different environments can create similar neural responses.
  3. New models, like causal graphs, allow for better understanding and planning in navigational tasks. They can adapt to new environments quickly by using learned sequences without needing to rely on exact spatial representations.
