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 ...
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
A combinatorial neural code for long-term motor memory Article Open access 13 November 2024 Introduction In everyday life we have to generate dexterous movements of limb joints to purposefully interact with variable environments. The mammalian primary motor cortex (M1) is known to contribute to con...
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,...
). 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 ...
