During behavior, many neurons do not have classic trial-averaged responses to behaviorally relevant stimuli, but can still have activity and population dynamics related to stimulus and behavioral choice on single trials.
Neuronal activity in the striatum keeps track of elapsed time during the time production task while that in the cerebellum correlates with stochastic variation of self-timing in the range of several hundreds of milliseconds.
As mice learn to associate events separated in time, neurons within the CA1 region of the hippocampus progressively reorganize their firing patterns, leading to a relay of cellular activity that bridges the two events.
Direct and indirect pathways in the basal ganglia have opposing effects not only on action performance but also on internal timing of expected reward delivery.
