Temporal prediction refers to the ability to anticipate when events will occur. Yet, it remains unclear whether this cognitive capacity relies on shared or context-dependent mechanisms across temporal regularity, modality, and task demands. Using a multi-task fMRI paradigm, temporal encoding for subsequent prediction engaged cortico–striatal–cerebellar regions as a function of these factors. Premotor and cerebellar regions formed a tightly coupled core cluster, sensory cortices showed modality-specific responses, and dorsal striatum exhibited strong task-dependent modulation and selective sensitivity to auditory beat-based timing. Although weaker, the cerebellum showed also a task effect but no beat-specific effects. These findings support a shared representation of temporal encoding underlying predictive timing alongside context-dependent specialization in subcortical circuits.
