Using an algorithm, the researchers then determined the reward prediction error for each choice -- the difference between an expected reward and the actual reward received.
Subjects whose reward prediction errors most closely matched activity in the nucleus accumbens also showed the most progress in learning the choices that led to the consonant tones.
"Our results demonstrate that musical events can elicit formally-modeled reward prediction errors like those observed for concrete rewards such as food or money, and that these signals support learning.
But Uchida and colleagues from Harvard and Beth Israel Deaconess Medical Center reported that reward prediction error is actually the product of a complex interplay between two classes of neurons - one that relies on dopamine and an inhibitory class of neuron that uses the neurotransmitter GABA.
The results, Uchida said, showed that while firing of dopamine neurons signalled reward prediction error, firing of GABA neurons signalled an expected reward.
Midbrain dopamine neurons encode a quantitative reward prediction error signal.
(2007) Reward prediction error signals associated with a modified time estimation task.
Surprise signals in anterior cingulate cortex: neuronal encoding of unsigned reward prediction errors driving adjustment in behavior.
For example, a reward prediction error might correspond to the difference between the projected monetary return on a financial investment and our real earnings.
This finding suggests that dopamine-producing neurons are signaling reward prediction errors instead of reward itself.
It is now almost universally accepted that bursts of dopamine neuron activity convey reward prediction errors to brain structures where learning and decision-making take place, and evidence supports the idea that the prediction errors might be TD errors.
