SciCafe: Forgetting Fear with Daniela Schiller

SciCafe: Forgetting Fear with Daniela Schiller

Q&As

Fear can take many forms, from minor phobias to life-altering conditions such as PTSD. Now, new research is shedding light on how these so-called fear memories could be changed. At the final SciCafe of the season on Wednesday, June 6,neuroscientist Daniela Schiller will discuss her work on the neural mechanisms of emotional control and potential ways to modify or “erase” fear memories. Schiller recently answered a few questions about how memories are created and lost.

How did you first become interested in studying emotional memories?

It wasn’t an explicit decision. I started with philosophy and psychology, and I was interested in the brain and the mind. And the combination is the neural basis of behavior, and within behavior, emotion is fascinating because it’s the least willful process we have. We think emotions just happen to us, but they don’t just pop out of the blue. It’s interesting to look at the mechanism and see that it’s a very distinct process in the brain that you can observe and counteract and modulate.

The Evolution of Skin

The Evolution of Skin

Q&As

Skin is the body’s largest organ, and one with a complex cultural and evolutionary past. At the upcoming SciCafe on Wednesday, May 2, biological anthropologist Nina Jablonski will discuss how human skin evolved, particularly as an adaptation to ultraviolet radiation. She recently answered a few questions about skin and its role in our lives.

When did you decide to study the history of human skin?

Nina Jablonski: By accident. About 23 years ago, a colleague asked me to give a lecture to his class about skin because he was going to be out of town for a conference. I obliged. In preparing for the lecture, I realized just how little had been written about the evolution and meaning of human skin.
