Article Synopsis
- Light is a key factor that influences body rhythms through the suprachiasmatic nucleus (SCN) in the hypothalamus, but social interactions also play a significant role in modulating these processes.
- A study with male mice showed that social isolation affected the dorsal part of the SCN, resulting in fewer active neurons when housed alone compared to those in groups, especially during light phases.
- The findings suggest that social interaction can mask the effects of light on SCN activity and help maintain consistency between body temperature and activity rhythms, highlighting the importance of both light and social factors in regulating circadian rhythms.

Article Synopsis
- Kisspeptin neurons in the RP3V are crucial for stimulating GnRH release, which triggers the LH surge during the estrous cycle in rodents.
- Noradrenaline (NA) plays a significant role in regulating GnRH release and is closely associated with kisspeptin neurons in this area.
- Administering prazosin, an α1-adrenergic receptor blocker, disrupted the expected increase of GnRH and kisspeptin levels before the LH surge, highlighting the importance of NA signaling in kisspeptin synthesis and its role in the timing of the preovulatory LH surge.
