Correlates of reward-predictive value in learning-related hippocampal neural activity.
Bottom Line: The results suggest that information about correct associations may be expressed in the hippocampus before it is detected in the behavior of a subject.In this way, the hippocampus may be among the earliest brain areas to express learning and drive the behavioral changes associated with learning.These potential functions are discussed in connection with hippocampal cell assembly sequences and their reverse reactivation during the awake state.

Mentions: For a given pair of α and γ, Eqs. (2)–(4) are iterated using one of the following three reward schedules: rk(T) = nk, rk(T) = 1, or rk(T) = 0, where the time T indicates the end of the trial and nk is the outcome of a subject's behavioral response such that nk = 1 if the response is correct, and nk = 0 otherwise, as shown in Figure 2. The reward signal is zero at all other times.
