The context-dependence of extinction learning has been well studied and requires the hippocampus. However, the underlying neural mechanisms are still poorly understood. Using memory-driven reinforcement learning and deep neural networks, we developed a m
The dynamics of memory: Context-dependent updatingA HupbachO HardtR GomezL NadelSynonyms Memory modification ; Memory reconsolidation Definition Memory updating is a phenomenon whereby, under certain conditions, new information can be incorporated into preexisting memories. Various aspects of the ...
By the definition of choice 1 and choice 2, a similar but opposite drift has to occur in neurons whose response field overlaps with choice 2 (the responses of which we did not record). In the framework of diffusion-to-bound models, such a drift can be interpreted as an urgency signal,...
(B) Neural activity was recorded from 6 cortical areas. The heatmap is the trial-averaged z-scored deconvolved activity of an example RSC population. The activity of each neuron was normalized to its peak. A half of the recorded trials were used to sort cells by the peak time, and the ...

Escape behaviors range from very simple reflex-like actions9,10,11 to more complex actions requiring cognitive processes that rely on memory and decision-making5,12,13. Animals must first decide whether to respond and then how to respond to threats. Both decisions could be affected by the type...
). There was a small shape in the centre of the screen as in the 0-back condition, but it was red. Participants had to indicate via button press which of the two shapes from the previous trial the central shape matched. Therefore, the decisions in this condition were guided by memory ...
