| summary | Value-based decision making requires generalising value using one's knowledge about structure in the environment. Humans excel in both, generalising value and inferring higher-order relationships between events in the environment from their statistical co-occurrence. I will represent several recent studies in which we leverage novel approaches to tap into neural replay using fMRI. These studies tested (1) whether it is feasible to detect fast sequential sequences with fMRI, (2) whether cortical replay is related to learning higher-order sequential relationships without consciousness and (3) whether hippocampal replay plays a role in generalising value based on known structure. Our findings show the principled feasibility of detecting fast neural sequences by analysing the temporal dynamics of multivariate with fMRI data. Using this method, we provide evidence that sequential replay of multi-step sequences in visual cortical areas are linked to human’s ability to acquire statistical multi-step transition knowledge. Finally, we report data from a value based decision making task in which replay is linked generalising value based on known structure. |
