⤴️​ After reading this #NeuroPaper I have to say it is much more interesting than what I thought at first view! And particularly well-written, illustrated and clear!

A must-read for anyone interested in #Dopamine #ReinforcementLearning #Reward #Value #RewardPredictionError #Navigation #Shortcuts #Detours #CognitiveMap (maybe) #Inference with some future hints of #HippocampalReplay !
Congrats to all authors, let me know if any is on here!

⤵️​3/5 Why P1 (‘Place cells in the 4-room’):

• Has #Rat SaloonDoors & bells
• Rats rapidly learn to avoid uncued locked doors
• Rats do flexible detours (most of the time) -> #CognitiveMap use?
• #PlaceCells do not remap to changes in connectivity: spatial, but not topological?
• They also do not over-represent doors!
• Place cells can represent space globally (individually and as a population) even when geometry repeats

Warm welcome (and happy new year) to our very own Lynn Nadel, now on Mastodon!! 🥳
