Uterine Fibroid Embolism Video-2

Uterine Fibroid Embolism and Interventional Radiology (Part 2)

Radiologists are known for looking inside the body to diagnose health problems. And now, many of these same doctors now use advanced

imaging equipment, not just to diagnose, but also to treat a wide range of problems. In this program, you'll learn how interventional

radiologists use minimally invasive techniques to help people with many conditions, including uterine fibroids and cancer.

Part Two:
Uterine fibroids - what are they?
Uterine fibroid symptoms
Uterine fibroid embolization
Treating pelvic pain

Guest:
Dr. Howard Richard, an interventional radiologist at the University of Maryland Medical Center. Dr. Richard is also an assistant professor of diagnostic radiology at the University of Maryland School of Medicine

Neurobiology of Fear, Anxiety and Extinction video

Neurobiology of Fear, Anxiety and Extinction: Implications for Psychotherapy
by:Dr. Michael Davis, Video from MIT

About the Lecture
Few scientists have charted the grim territory of fear and anxiety with the same doggedness and precision as Michael Davis.

Nearly four decades ago, researchers learned that animals, including humans, startle more when fearful. A sudden noise in a dark, creepy alley provokes a greater reaction than in a well-lit room, for instance. That got Davis and his colleagues wondering what neural mechanisms underlie the startle reflex, and how fear plays a part in the response.

In his talk, Davis describes the meticulous experiments he and others have conducted over many years. Starting with the fear potentiated startle test -- where animals are trained to pair a stimulus such as light, or sound, with a shock -- researchers began to track the pathways that mediate the response in the nervous system. Using chemical tracers that could follow electrical activity in the brain, Davis found a group of cells in the central nucleus of the amygdala that are critical for fear conditioning. “It was a nice day in the laboratory,” he says. When he knocked out this part of the amygdala with drugs or a lesion, it selectively decreased fear potentiated startle.
