A New York based research team has come out with the conclusion that small group of neuron which respond to Oxytocin hormone play key role in controlling sexual behaviour. The study was conducted on mice and the results have been published in Journal Cell.
It was already known that Oxytocin is the main hormone when it comes to sexual stimulus. The hormone is famously known as ‘love hormone’. The current study has confirmed this observation.
The scientists associated in the research later switched off the discovered neurons and the mice stopped showing signs of sexual attraction towards their male counterparts.
These neurons are located in the prefrontal Cortex region, an area which is known to control the learning ability, personality and social behaviour. An interesting observation which came out during the study was that as the Oxytocin hormone were withheld and the cells silenced, the interest in mating was lost by the female. Again as the hormones were released, the female showed normal interest in the males.
The co-author of the study, Nathaniel Heintz, who also happens to be the Professor in Rockefeller University in New York, was visibly excited about the discovery. The study according to Nathaniel was significant as the cells found were specific and very small.
Professor Gareth Leng from University of Edinburg pointed out that Oxytocin has the ability of bring alternation in ways neurons interact with each other. It effectively carries out the functional rewiring. He further elaborated that Oxytocin is more like a hormone with the brain itself.
