We begin the show today with an update on the resignation of Baltimore City Police Commissioner Daryl DeSousa. WYPR reporter Dominique Maria Bonessi attended Mayor Catherine Pugh’s press conference this morning. She joins Tom in Studio A.Tom’s guest for most of the hour is David Linden. He’s a professor of Neuroscience at the Johns Hopkins School of Medicine and the former editor of the Journal of Neurophysiology. Linden writes books about our brains, and in his latest opus, he says the public is “inundated by a fire hose of neuro BS.”He wrote the new book, called Think Tank, with more than three dozen fellow neuroscientists. It’s a collection of essays about our brains and the biological roots of human experience. The essays address questions such as, “How are children’s brains different from those of adults?” “What can monkey brains teach us about advertising?” And “How do our brains process pain?”David Linden and a few of the book’s contributors will hold a panel discussion about the book tomorrow afternoon at 1pm at the Johns Hopkins School of Medicine Department of Neuroscience, and you can also catch Linden at Greedy Reads in Fells Point on June 4 at 7 pm.We livestreamed today’s show on the WYPR Facebook page.
