Reward prediction error computation in the pedunculopontine tegmental nucleus neurons.
In this article, we address the role of neuronal activity in the pathways of the brainstem-midbrain circuit in reward and the basis for believing that this circuit provides advantages over previous reinforcement learning theory. Several lines of evidence support the reward-based learning theory proposing that midbrain dopamine (DA) neurons send a teaching signal (the reward prediction error sig...
متن کاملPedunculopontine tegmental nucleus neurons provide reward, sensorimotor, and alerting signals to midbrain dopamine neurons.
Dopamine (DA) neurons in the midbrain are crucial for motivational control of behavior. However, recent studies suggest that signals transmitted by DA neurons are heterogeneous. This may reflect a wide range of inputs to DA neurons, but which signals are provided by which brain areas is still unclear. Here we focused on the pedunculopontine tegmental nucleus (PPTg) in macaque monkeys and charac...
متن کاملReward prediction-related increases and decreases in tonic neuronal activity of the pedunculopontine tegmental nucleus
The neuromodulators serotonin, acetylcholine, and dopamine have been proposed to play important roles in the execution of movement, control of several forms of attentional behavior, and reinforcement learning. While the response pattern of midbrain dopaminergic neurons and its specific role in reinforcement learning have been revealed, the roles of the other neuromodulators remain elusive. Repo...
متن کاملIndependent neural coding of reward and movement by pedunculopontine tegmental nucleus neurons in freely navigating rats.
Phasic firing of dopamine (DA) neurons in the ventral tegmental area (VTA) and substantia nigra (SN) is likely to be crucial for reward processing that guides learning. One of the key structures implicated in the regulation of this DA burst firing is the pedunculopontine tegmental nucleus (PPTg), which projects to both the VTA and SN. Different literatures suggest that the PPTg serves as a sens...
