Two-dimensional localization of theta-related changes in the SuM/MM area. (A) The change of SuM/MM theta power relative to HPC changes in a coronal plane collapsed through three anterior-posterior planes. Warmer colors indicate more “sensitivity” (i.e., relatively more SuM/MM theta power decrease compared to HPC) to MS-inactivation. (B) Same layout as (A), but colors indicate the magnitude and direction of dominant theta frequency changes seen in the SuM/MM comparing post- and pre-MS-inactivation. (C) Correlating relative SuM/MM theta power changes to the HPC and the change in dominant SuM/MM theta frequency after MS-inactivation. HPC, hippocampus; SuM, supramammillary nucleus; MM, mammillary bodies; ML, medio-lateral; DV, dorso-ventral.
