Thus, the dopamine responses at the time of reward probe the reward prediction that exists at that moment. http://bsdupdates.com/prediction-error/prediction-error-formula.php These failures could reflect methodological issues.

Omission of expected footshock was also associated with reduced theta power compared with the CS+ period (and the pre-CS+ period), and this reduction was focused within the same narrow frequency band Prediction Error Statistics Definition

Note that the regression weights shown in Figure 8E indicate that, for rewarded trials, the firing rate of the neuron encoded information about the reward history, while for unrewarded trials, the From these proportional spectra, we determined the peak power in the theta frequency range (5–10 Hz) as shown in Figure 1F. However, for trials with reward interval firing rates below baseline, the neuronal firing rate was correlated only with the current reward and a constant offset term (not shown in the figure) Reward Prediction Error Wiki Science 299: 1898-1902, 2003 Hassani OK, Cromwell HC, Schultz W.

LFPs. The positive and negative reward prediction error response is also graded, such that a partial prediction error induces a smaller error response. The responses covary with the expected value of reward, irrespective of spatial position, sensory stimulus attributes and arm, mouth and eye movements ( Figure 6). Dopamine responses comply with basic assumptions of formal learning theory.
