This week we present four of our favorite stories of all time.

Part 1: Neuroscientist David Carmel tests his own understanding of the brain when his own father suffers a stroke.

Part 2: Ralph Bouquet goes off script during a psychology research study with uncomfortable and revealing consequences.

Part 3: Feeling isolated in her new job as a particle accelerator operator at Fermilab, Cindy Joe finds comfort in the friendship of her unconventional pet.

Part 4: To discover why some survivors of trauma experience PTSD and some don't, scientist Rachel Yehuda must convince a community of Holocaust survivors to let her study them.

David Carmel grew up reading Oliver Sacks and loving the weird stories of what goes wrong in people's brains, so he became a neuroscientist. He spends his days trying to figure out how the brain creates consciousness, and his nights trying to remember why he ever thought he could accomplish this. He is a Senior Lecturer in the School of Psychology at Victoria University of Wellington.

Ralph Bouquet is the Director of Education and Outreach for NOVA, the PBS science documentary series produced by WGBH in Boston. At NOVA, Ralph’s team supports science educators through the creation of free classroom resources and finds creative ways to engage new audiences for NOVA’s broadcast and digital productions through science communication events around the country. Before NOVA, Ralph taught high school biology and chemistry in Philadelphia and then spent some time in ed-tech at a Boston-based startup. Ralph received his B.A. from Harvard University, and studied secondary science methods and urban education while completing his M.Ed. at UPenn.

Cindy Joe is an engineering physicist at Fermilab, America’s particle physics and accelerator laboratory. She got her bachelor’s degree in physics and became a licensed senior nuclear reactor operator at Reed College in Portland, Oregon. After starting at Fermilab, she worked as a particle accelerator operator for seven years before taking her current role with several experiments studying neutrinos, tiny particles that might hold the answers to some of the universe’s biggest mysteries. Cindy is a frequent and deeply passionate contributor to Fermilab’s educational outreach programs and has spoken to audiences from elementary school students to members of Congress.

Rachel Yehuda is a professor of psychiatry and neuroscience at the Icahn School of Medicine at Mount Sinai and Director of the Mental Health Patient Care Center at the James J. Peters Bronx Veterans Affairs hospital. Her research on PTSD has included both human populations and animal models, neuroendocrinology, neuronal stimulations studies with human stem cells, and genomic and molecular biological studies of trauma. She has recently established a Center for Psychedelic Psychotherapy and Trauma at Mount Sinai.
