This week's episode has a slightly different concept, in the sense that it is medical. However, researchers in the psychology field have found it super fascinating and are using fMRIs to figure out all sorts of questions surrounding the brain. We relate fMRIs to the strange case of Brian Dugan, who was the first to use this type of scan in a criminal case. https://my.clevelandclinic.org/health/diagnostics/25034-functional-mri-fmrihttps://www.med.wisc.edu/news/psychopaths-brains-differences-structure-function/https://www.sciencedirect.com/science/article/pii/S0149763424003737https://www.ndcn.ox.ac.uk/divisions/fmrib/what-is-fmri/introduction-to-fmrihttps://academic.oup.com/scan/article/1/2/158/2362915https://murderpedia.org/male.D/d/dugan-brian-james.htmhttps://law.stanford.edu/2009/12/14/neuroscience-and-sentencing-diminished-culpability-and-capacity-for-change/https://www.science.org/content/article/fmri-evidence-used-murder-sentencinghttps://www.criminallawlibraryblog.com/fmri_evidence_used_in_murder_sentencing/https://www.dailyherald.com/20091105/news/strange-mind-of-a-killer-researcher-says-dugan-rare-psychopath/https://www.steme.org/post/science-behind-psychopathyhttps://www.nature.com/articles/464340a
