"To our surprise, these animals that were completely lacking oxytocin receptor showed, for all intents and purposes, perfectly normal social attachment behaviours," Shah said.

In animals with social structures, the drive to reproduce is a complex process; governed by the brain, it's influenced by both internal cues such as hormones and external factors such as interactions ...

However, high levels of oxytocin could, I theorize, lead to overinterpretation of emotional cues in social interactions. If you’re already prone to social anxiousness, increasing your ...

But selection can also act on the genes that code for receptors (in the case of the androgen receptor, the number of glutamine units specified inversely determines sensitivity to testosterone ...

Since these cells expressed oxytocin receptors, the team next sought the source of oxytocin for the aVMHvl neurons. By mapping the expression of c-fos and oxytocin after defeat, the researchers found ...

The dogs performed this behavioral test twice, once after receiving a dose of oxytocin nasal spray, and once after receiving a dose of neutral saline nasal spray. The team timed the dogs to see ...

This suggests that oxytocin may trigger insulin production through a separate, receptor-dependent pathway involving the hormone GLP-1. "WT mice showed a significant increase in insulin levels at ...

Less well-known is that oxytocin can also affect pain perception. When the peptide hormone oxytocin binds to these receptors, it triggers a signal that reduces pain signals in the gut.
