Abstract

In this paper, we proposed a computational theory of human memory formation in the hippocampus and determined if electroencephalography (EEG) theta power is associated with eye saccades during object-place memory encoding. EEG theta power and saccade rate is significantly correlated with subsequent recall performance. This result suggests that information acquisition for object-place memory is processed by the theta rhythm network for memory system, attentional regulation and saccades.
