Abstract: Animal studies have shown that the prediction error (PE) signal that drives fear extinction learning is encoded by phasic activity of midbrain dopamine (DA) neurons. Thus, the extinction PE resembles the appetitive PE that drives… read more here.

Abstract: Significance Theories of cerebellar-dependent motor learning use the error between the desired and actual movement to correct the erroneous movement. To support this idea, several studies have tried to eliminate the error signal to the… read more here.

DOI: 10.1093/schbul/sbaa028.052
Abstract: Abstract Background Prediction error is the mismatch between expected and obtained outcome, and psychosis has been linked to aberrant striatal prediction error signal. Several lines of evidence indicate alterations of the glutamatergic system to be… read more here.
