Rosie Brown Laboratory

Research interests

I am interested in how the changing hormones of pregnancy and lactation act on neural circuitry in the maternal brain to influence behaviour. In particular, I focus on maternal behaviour, a complex set of behaviours displayed by a mother that promote the survival and wellbeing of her offspring. Our work aims to understand how hormones normally act to direct a mother’s behaviour and how these processes may become disrupted.
At the Centre for Neuroendocrinology, I use transgenic mouse models to address the impact of specific neuroendocrine disruptions on maternal behaviour using behavioural assays. We investigate hormonal actions on neural circuitry underlying parental behaviour using a range of molecular, immunohistochemical and imaging approaches.
I am also interested in how changes in the ability of hormones to access the brain in different physiological or pathological states might underlie changes in hormone function.
