Cognitive neuroscience: How the brain navigates abstract task spaces
Humans and other animals learn the abstract structure of a task and then use this
structure to rapidly generalize to new situations. A recent study reveals how the
brain builds and uses abstract task ...

Large-scale interactions in predictive processing: oscillatory versus transient dynamics
How do the two main types of neural dynamics, aperiodic transients and oscillations, contribute to the interactions between feedforward (FF) and feedback (FB) pathways in sensory inference and predictive processing? We discuss three theoretical perspectives. First, we critically evaluate the theory that gamma and alpha/beta rhythms play a role in classic hierarchical predictive coding (HPC) by mediating FF and FB communication, respectively. Second, we outline an alternative functional model in which rapid sensory inference is mediated by aperiodic transients, whereas oscillations contribute to the stabilization of neural representations over time and plasticity processes. Third, we propose that the strong dependence of oscillations on predictability can be explained based on a biologically plausible alternative to classic HPC, namely dendritic HPC.
