We often perceive memories as unified experiences although they comprise a multiplicity of different modalities and features. How the different aspects of a memory are encoded separately or jointly in the brain’s memory systems is not well understood. A key brain structure that has been identified to be involved in processing emotional memories is the ventral hippocampus. In our study we use virtual environments to induce in head-fixed mice the recall of distinct memories of a trace fear conditioning, consisting of a cue-triggered temporal and a context-triggered emotional component. To investigate the underlying circuits for these memories we are recording with silicon probes from the ventral hippocampus while we are simultaneously monitoring the emotional state of the mice with behavioural readouts on locomotion, pupil size and breathing rhythms. We find that the fear-related cue and context induce a general ventral hippocampal activation of pyramidal neurons and interneurons. Further, the majority of pyramidal neurons and notably also interneuron populations represent different emotional and mnemonic features including cue, context and anticipation while some fewer neurons could bridge between the different memories. Considering the diversity of interneuron cell types in the hippocampus we are determining how the different emotion-related interneuron populations relate to network oscillations and investigate their cell type identities. In order to achieve this we have recently established the juxta-cellular recording and labelling technique in our lab to reveal principles of emotional memory encoding in the ventral hippocampus.
