Calling all athletes reporting for practice! Returning to the show are James Hicks, UCI professor and Director at Center for Exercise Medicine and Sport Sciences; and Michael Yassa, UCI Professor of Neurobiology and Behavior, and Director of the Center for Neurobiology of Learning and Memory. They take up their research along the continuum from the benefits to the hazards of exercise on brain health. Of concern are NFL bangs, the disparities of women in research trauma, and men versus women’s response to trauma and lots in between. Resources galore are available at: http://emssi.uci.edu/ and http://yassalab.org/.
