Caption: Professor Allan Herbison is leader of a team discovering that neural circuitry they previously showed was vital to triggering ovulation also plays a key role in moulding the male brain. They have found that male-specific signalling in the Gonadotropin-releasing hormone (GnRH) neurons of new-born mice is crucial to generating a testosterone surge that occurs up to five hours after birth. This brief but powerful increase in testosterone blood levels, which only takes place in males, is known to cause their brains to develop differently to females.
