Higher HPC theta frequency is related to a higher SuM/MM to HPC drive. (A) Paired comparisons of dominant HPC and SuM/MM theta frequency. (B) Paired comparisons between theta PDC estimates for HPC to SuM/MM (H2M) and the opposite direction (M2H). (C) Difference between HPC and SuM/MM dominant theta frequency is plotted against the difference between H2M and M2H PDC estimates (i.e., overall causal influence). CoM, center of mass; PDC, partial directed coherence; H2M, mean HPC->SuM/MM theta PDC; M2H SuM/MM->HPC theta PDC; H-M, HPC-SuM/MM PDC difference score; SuM, supramammillary nucleus; MM, mammillary bodies.
