Include some kind of methods on poster presentation (ex: fmri study: neurobiology of mental illness. Several techniques to detect a genetic contribution to disease interaction with stressful event and genetic predisposition. Techniques to study mental illness and nature vs nurture. Got group of rats, normal distribution of ability to navigate maze. One tail- rats that do really well, other tail rats that do really poor. Breed tails with like tails with several generations. After 8 generations= two complete distinct populations of rats. Rats that were really good (maze bright) and really bad (maze dull. ) Look for differences in variant of genes or gene expression (look for extreme in genes and compare with ) in those with disease vs normal. Early work isolate from sample of tissue the chromosomes from individual and look at under the microscope. Can discern really large differences in chromosomes. Ex: extra chromosome on 21st pair. (three copies. )
