 place cells has garnered interest in their sensitivity to changes in the a
 nimal’s environmental cues\, past experience\, and even internal states\
 , in a process called remapping. Muller and Kubie (1987) document enlighte
 ning but unpredictable remapping of firing fields while changing the size 
 and salient features of an animal’s enclosure. Plitt and Giocomo (2021) 
 frame remapping in a Bayesian setting\, forming the animal’s prior over 
 environmental cues by changing the frequency of their appearance during tr
 aining. The impact on subsequent responses suggests remapping is used to b
 oth map location and optimally infer environmental variables. Finally\, Lo
 w et al. (2023) compare the ring attractor dynamics developed by an RNN tr
 ained to simultaneously track both location and an internal state\, to neu
 ral data of mice undergoing spontaneous remapping\, i.e. remapping in resp
 onse to internal rather than navigational features.\n\nReferences:\n\n[1]
