Psychiatrist Bessel van der Kolk is an innovator in treating the effects of overwhelming experiences. We call this “trauma” when we encounter it in life and news, and we tend to leap to address it by talking. But Bessel van der Kolk knows how some experiences imprint themselves beyond where language can reach. He explores state-of-the-art therapeutic treatments — including body work like yoga and eye movement therapy — and shares what he and others are learning on this edge of humanity about the complexity of memory, our need for others, and how our brains take care of our bodies.

Science writer and reporter Erik Vance says today’s brain scientists are like astronomers of old: They’ve unsettled humanity’s sense of itself by redrawing our picture of the cosmos within our own heads. Vance has investigated the healing power of stories and the “theater of medicine” (white coats included). It turns out that the things that make us feel better are often more closely connected to what we believe and fear than to the efficacy of some treatments. In fact, most drugs that go to trial can’t beat what we’ve dismissively called the “placebo effect,” which is actually nothing less than an unleashing of the brain’s superpowers.

Neuroscientist Richard Davidson is one of the central people who’s helped us begin to see inside our brains. His work has illuminated the rich interplay between things we saw as separate not that long ago: body, mind, spirit, emotion, behavior, and genetics. Richard is applying what he’s learning about imparting qualities of character — like kindness and practical love — in lives and in classrooms. This live conversation was recorded at the Orange County Department of Education in Costa Mesa, California.

With his book Thinking, Fast and Slow, Daniel Kahneman emerged as one of the most intriguing voices on the complexity of human thought and behavior. He is a psychologist who won the Nobel Prize in economics for helping to create the field of behavioral economics — and is a self-described “constant worrier.” It’s fun, helpful, and more than a little unnerving to apply his insights into why we think and act the way we do in this moment of social and political tumult.

Jean Berko Gleason is a living legend in the field of psycholinguistics — how language emerges, and what it tells us about how we think and who we are. She has helped to illustrate the remarkable ordinary human capacity to begin to speak, and she’s continued to break new ground in exploring what this may teach us about adults as about the children we’re raising. We keep learning about the human gift, as she puts it, to be conscious of ourselves and to comment on that. For her, the exploration of language is a frontier every bit as important and thrilling as exploring outer space or the deep sea.

Few features of humanity are more fascinating than creativity; and few fields are more dynamic now than neuroscience. Rex Jung is a neuropsychologist who puts the two together. He’s working on a cutting edge of science, exploring the differences and interplay between intelligence and creativity. He and his colleagues unsettle long-held beliefs about who is creative and who is not. And they’re seeing practical, often common-sense connections between creativity and family life, aging, and purpose.

Alzheimer’s disease has been described as “the great unlearning.” But what does it reveal about the nature of human identity? What remains when memory unravels? Alan Dienstag is a psychologist who has led support groups with early Alzheimer’s patients, as well as a writing group he co-designed with the novelist Don DeLillo. He’s experienced the early stages of Alzheimer’s as a time for giving memories away rather than losing them.

What Adele Diamond is learning about the brain challenges basic assumptions in modern education. Her work is scientifically illustrating the educational power of things like play, sports, music, memorization, and reflection. What nourishes the human spirit, the whole person, it turns out, also hones our minds.

Dr. Sherwin Nuland died this week at the age of 83. He became well-known for his first book, How We Die, which won the National Book Award. For him, pondering death was a way of wondering at life — and the infinite variety of processes that maintain human life moment to moment. He reflects on the meaning of life by way of scrupulous and elegant detail about human physiology.
