Abstract

My laboratory focusses on how neuronal networks, with their origin in the hypothalamus, drive and organize instinctive behaviours such as aggression, feeding and reproduction. We recently addressed the poorly understood issue of how paternal care of offspring is controlled by brain circuits. By combining a wide range of techniques, we capitalize on a recently identified species difference in the network rhythm of neuroendocrine dopamine neurons, which echoes throughout the release properties of these cells, through the hormone axis and activation of brain control centres for parental behaviour, to explain why mouse fathers share in looking after pups, whereas rats are maternally uniparental. These findings provide a model for the brain-endocrine control of paternal behaviour, and offer novel insight into how different frequencies of brain oscillations can have a direct impact on the behavioural phenotype of a species.
