OXYTOCIN - SCIENCE AND TECHNOLOGY

News: A fish can sense another's fear, a study shows

 

What's in the news?

       The new study shows that fish can detect fear in other fish, and then become afraid too – and that this ability is regulated by oxytocin, the same brain chemical that underlies the capacity for empathy in humans.

 

Key takeaways:

       The researchers demonstrated this by deleting genes linked to producing and absorbing oxytocin in the brains of zebrafish, a small tropical fish often used for research.

       Those fish were then essentially antisocial – they failed to detect or change their behaviour when other fish were anxious.

 

Oxytocin:

       It is a female hormone.

       It has also been dubbed the love hormone, hug hormone, cuddle chemical, moral molecule, and the bliss hormone due to its effects on behavior, including its role in love and in female reproductive biological functions in reproduction.

 

Produced from:

       Oxytocin is a hormone that is made in the brain, in the hypothalamus.

       It is transported to, and secreted by, the pituitary gland, which is located at the base of the brain.

 

Features:

       It acts both as a hormone and as a brain neurotransmitter.

       The release of oxytocin by the pituitary gland acts to regulate two female reproductive functions - Childbirth and Breast-feeding.
