Please join us for our fortnightly journal club online via zoom where two presenters will jointly present a topic together. The next topic is ‘Hippocampal remapping and contextual inference’ presented by Puria Radmard and David Liu.

Zoom information: https://eng-cam.zoom.us/j/84204498431?pwd=Um1oU284b1YxWThObGw4ZU9XZitWdz09 Meeting ID: 842 0449 8431 Passcode: 684140

Summary: The location-specific firing of hippocampal place cells has garnered interest in their sensitivity to changes in the animal’s environmental cues, past experience, and even internal states, in a process called remapping. Muller and Kubie (1987) document enlightening 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 training. The impact on subsequent responses suggests remapping is used to both map location and optimally infer environmental variables. Finally, Low et al. (2023) compare the ring attractor dynamics developed by an RNN trained to simultaneously track both location and an internal state, to neural data of mice undergoing spontaneous remapping, i.e. remapping in response to internal rather than navigational features.
