The development of sexually dimorphic behaviour
The development of sexually dimorphic behaviour
This chapter examines the function of hormones in determining sexually dimorphic behaviour development in male and female primates during foetal development, infancy, and puberty. It presents the neuroanatomical basis of sexually dimorphic behaviour and explores sex differences in the primate brain including corpus callosum, preoptic area, anterior hypothalamus and other hypothalamic nuclei. The chapter argues that because primates are precocial, the effects of testosterone are likely to occur during prenatal development. It then examines neuroendocrine and behavioural changes during puberty such as development of the hypothalamic-pituitary-gonadal and behavioural effects of hormones specifically their organization and activation.
Keywords: hormones, sexually dimorphic behaviour, corpus callosum, preoptic area, anterior hypothalamus, hypothalamic nuclei, puberty
