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.Correlates of reward-predictive value may be expressed in the hippocampus through rate remapping within spatial memory representations, they may represent reward-related aspects of a declarative or explicit relational memory representation of task contingencies, or they may correspond to reward-related components of episodic memory representations.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.
