μ is the size of the step which is modulated by the error obtained, so that the global step is adaptive: the larger the error the more the radius is increased/decreased.
None of these studies modulated the perceived error-likelihood via different learning modes.
In other words, precision modulates the gain of prediction error in driving changes in conditional representations or expectations.
The estimate of spatiotemporal complexity is employed to modulate the propagation of the IVA in the error propagation model.
The error signal can, in turn, modulate the motor command [27].
It has been hypothesized that the error negativity (Ne or ERN) is modulated by the midbrain dopaminergic system.
If membrane voltage corresponds to the error, then ion channels contributing prior information (layer 2) should modulate their activity in order to drive voltage towards the middle of its range where the error is zero (Fig. 2).
Congruently, it has been reported earlier that the error positivity, an ERP closely related to the feedback P3, is modulated by COMT.
