Action understanding in the predictive coding framework. a, Sensory information is propagated through the early visual cortex (EVC; green circle), pSTS (orange circle), parietal cortex (yellow circle), and premotor cortex (pink circle) via feedforward connections (blue arrows), whereas prior information is propagated in the opposite order via feedback connections (red arrows). Possible sources of prior information are depicted with large arrows oriented to vPMC: the purple arrow represents a prefrontal source for prior information, which was suggested by Maranesi et al. (2014), and the light green arrow represents a thalamocortical source that may contribute. b, Depiction of representation units and error units at all levels of the mirror neuron system. Sensory information is fed into the system from the early visual cortex and propagated through feedforward connections (blue arrows). Predictions, originating from prior information, are propagated via feedback connections (red arrows). Prior information originates either from prefrontal cortex (purple arrow) or early visual cortex mediated via thalamic projections (green arrow). Bidirectional red arrows between the error units and representation units indicate the computation of prediction error signal. Prediction error signals are used to update the predictions, which are then fed to the error units of the next level of the cortical hierarchy (blue arrows).
