BIOS 286 Lecture Notes - Lecture 13: Testicle, Pituitary Gland, Neurochemistry
Document Summary
Sexual reproduction depends on a variety of individual and social behaviors. These behaviors of males and females are usually quite different. Male and female brains are also somewhat different. The size of a particular structure or subnucleus. The number of synapses made between neurons in a particular brain region. The neurochemical phenotype of neurons in a particular brain region. The activation of physiology of neurons in a particular brain region, at rest or in response to stimuli (fmri) To understand the cultural influences on sex differences in brain and behavior, we have to understand the biological influences first. X contains 800 genes, and y contains 50 genes. A human with a y chromosome and the sry gene develops as a male. Without sry, the individual develops as a female. If there is a sry gene, the wolffian duct develops into the male reproductive organs (testes)
