Reward, motivation and reinforcement learning

Abstract
There is substantial evidence that dopamine is involved in reward
learning and appetitive conditioning. However, the
major reinforcement learning-based theoretical models of
classical conditioning (crudely, prediction learning) are
actually based on rules designed. Extensive
anatomical, pharmacological, and psychological data,
particularly concerning the impact of motivational manipulations,
show that these models are unreasonable. We review the data and consider the
involvement of a rich collection of different neural systems in
various aspects of these forms of conditioning.
Dopamine plays a
pivotal, but complicated, role.
