Fees and funding
Fees
Tuition fees for home students commencing their studies in September 2025 will be £9,535 per annum (subject to Parliamentary approval). Tuition fees for international students will be £34,500 per annum. For general information please see the undergraduate finance pages.
Additional expenses
Policy on additional costs
All students should normally be able to complete their programme of study without incurring additional study costs over and above the tuition fee for that programme. Any unavoidable additional compulsory costs totalling more than 1% of the annual home undergraduate fee per annum, regardless of whether the programme in question is undergraduate or postgraduate taught, will be made clear to you at the point of application. Further information can be found in the University's Policy on additional costs incurred by students on undergraduate and postgraduate taught programmes (PDF document, 91KB).

Overview
This course defines how endocrine and brain circuits control sexual, affiliative and aggressive behaviour. Students are introduced to comparative examples from the animal kingdom and underlying genetic mechanisms, as well as neuroendocrine circuits and peptide relays in the brain. Where possible, examples are drawn from the medical literature to indicate the common nature of these processes in our own species, and governing our behaviour.

Aims
This course defines how endocrine and brain circuits control sexual, affiliative and aggressive behaviour. Students are introduced to comparative examples from the animal kingdom and underlying genetic mechanisms, as well as neuroendocrine circuits and peptide relays in the brain. Where possible, examples are drawn from the medical literature to indicate the common nature of these processes in our own species, and governing our behaviour.
Learning outcomes
To teach student how brain circuits and evolutionary forces have moulded the social and sexual behaviour of man and animals.
Syllabus
Setting the scene: Sexual Dimorphism of the Brain and the role of sex steroids. Discovery of aromatization mechanisms and local oestrogen concentrating neurons. Implications of mutations in these pathways in animals and man. The hypothalamus as a key regulator of the endocrine system. Hypothalamic peptides as releasing hormones and as neurotransmitters - examples of GnRH (sexual behaviour) and Oxytocin/Vasopressin (affiliative behaviour). We the move on to define how sexual differentiation mechanisms define sexual behaviour, from the concept of switches on chromosomes, consequences of sex reversal in man and animals and gender identity. We next move to Africa and studies in animals of sexual mimicry, including the famous example of the spotted hyena, and the strange case of the enlarged clitoris and false testis (!), and how mutations in steroid metabolism pathways may drive this process. In birds, we enter the looking glass world where females are the heterogametic sex, and consider hormonal and primary genetic mechanisms controlling singing, sexual behaviour, plumage development and brain differentiation. Hot tempered alligators are animals without sex chromosomes, so we look at reptiles and how the environment controls brain and behaviour. We also look at weapons of war, and sexual aggression and its control by hormones.
In mammals, we move to the story of how two closely related peptide hormones control sexual and affiliative behaviour in females and males - the endocrinology of love and consider their role in man. The early environment matters, and we consider the remarkable evidence that maternal behaviour affects the wiring and organisation of chromosomes in mammals, with long-term effects on stress, including man. We move to Australia to consider the remarkable story of the marsupial mouse, Antechinus, where the males all die within a week or so of mating, and link this to brain stress pathways. We then move to strange world of genomic imprinting, where genes are suppressed or activated depending on which parent you inherited them from - the study of epigenetics and behaviour. Lastly, we move back to Africa, and look at our nearest relatives the Great Apes, and consider similarities and differences in their sexual behaviour and that of man. To finish, we go underground, and explore the extraordinary sex life of the naked mole rat.
