We <strong><span style=\"color: #ff0000;\">examine whether rat hippocampal neurons may encode the behavior of a minirobot, but without requiring the animal to mimic it<\/span><\/strong>. Rather than finding social place cells, we observe that robot behavioral patterns modulate place fields coding animal position. This modulation may be confounded by correlations between robot movement and changes in the animal\u2019s position. Although rat position indeed significantly predicts robot behavior, <strong><span style=\"color: #ff0000;\">we find that hippocampal ensembles code additional information about robot movement patterns<\/span><\/strong>. Fast-spiking interneurons are particularly informative about robot position and global behavior. <strong><span style=\"color: #ff0000;\">In conclusion, when the animal\u2019s own behavior is conditional on external agents, the hippocampus multiplexes information about self and others.<\/span><\/strong>&#8220;<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/marlin-prod.literatumonline.com\/cms\/attachment\/ba286e75-7093-4164-b898-1036b5bb709d\/fx1.jpg\" \/><\/p>\n<p style=\"text-align: center;\">The fig. is from Bos et al. 2019<\/p>\n<p style=\"text-align: justify;\">Bos, Jeroen J., Martin Vinck, Pietro Marchesi, Amos Keestra, Laura A. van Mourik-Donga, Jadin C.
