The entorhinal cortex is an area known to be involved in spatial navigation and episodic memories. While the spatial aspects of episodic memories have been studied in great detail, questions still remain regarding the processing of social information in the brain.Emerging evidence points towards a complex network of brain areas involved in social memory processing. In particular, the hippocampal regions CA2 and ventral CA1 play an important role, but the role of computations within the hippocampus compared to the input regions remains unresolved. With entorhinal cortex being the main input region to the hippocampus, providing spatial and non-spatial information, a remaining question is whether this area also takes part in social memory processing.Using implanted tetrodes, we record local field potential and single unit activity from the lateral (LEC) and medial entorhinal cortex (MEC) in rats during a social recognition task. To disentangle social, object and spatial coding, rats are also tested in an object recognition task. Preliminary results show that units in the LEC show a diverse tuning exhibiting both spatial and non-spatial activity patterns. Interestingly, a subset of neurons in LEC shows preferential firing in the interaction zones containing social stimuli. In contrast, grid cells in MEC show a stable spatial coding during the social recognition task.Ongoing analyses of single cell and population activity will reveal associations to the social stimuli, object recognition and spatial context.
