Research Abstract |
The ventral tegmental area(VTA) contains dopamine neurons that are important in modulating motivated behavior, addiction, and reward. Here, we show that VTA dopamine neurons express GnIH receptor mRNA and receive synaptic input that contains gonadotropin-inhibitory hormone(GnIH). Furthermore, we examined changes in the activity of GnIH neurons in the brain of male following a view of and sexual interaction with a female. The presence of female seems to result in a change in diencephalic GnIH mRNA levels of male. These data support a new role for central GnIH with possible implications for regulation of sexual motivation
