Charles E. Roselli,US neuroendocrinologist,with brain samples from female sheep (ewes) and male sheep (rams). The brains are from sheep that were studied as part of research into sex hormones and sexual orientation. Roselli works at the Oregon Health and Science University (OHSU),Portland,Oregon,USA. He specialises in the study of sex hormones in the brain. His experiments include the effect of testosterone on sheep brains,producing differences in reproductive behaviours between the sexes. It is thought that this can lead to differences between the sexes in brain diseases and psychiatric conditions. Photographed in 2013 | |
