Topic: single-cell Ca2+ imaging

Mammalian reproduction is highly energy intensive, and requires an animal to prioritize feeding or sociosexual interaction, depending on need and opportunity. We have recently shown that two leptin-sensitive populations – leptin receptor-expressing (LepRLH) and neurotensin-expressing (NtsLH) neurons of the lateral hypothalamus – act in a complementary manner to enable resistance to hunger and gate the pursuit of social needs (Petzold et al., Cell Metab 2023).Currently, using single-cell Ca2+ imaging in freely moving mice, we found that LepRLH neurons not only preferentially encoded conspecific
