While the earliest reliable noninvasive method, electroencephalography (EEG), used electrical signals to localize and quantify brain activity, measures of metabolic activity using positron emission tomography (PET) and single photon emission computed tomography (SPECT) followed a few decades later in the 1960s.7 EEG studies had exceptional benefits for revealing cognitive processing on the subsecond level, localizing epileptogenic foci, and monitoring patients with epilepsy. Penfield's corticography work enabled even more accurate measurements from recordings made directly from the cortex during neurosurgery.8 PET and SPECT have been used widely in basic research studies of neurotransmission and protein synthesis, further advancing our knowledge of neurodegenerative disorders, affectiv...

The department was desperate for recruits. Masses of officers had retired just as the city's population boomed, and the usual recruiting pool was away fighting two wars. Everywhere you looked - on billboards, in the paper, on the Web- HPD had posted help-wanted signs. "Be a Hero!" the message went. "You, too, can become a real hero." "Heroes Start Here!" It's hard to explain the effect these ads had on me, but the truth is, I'd always wanted to be a hero. With the cops offering "a competitive salary," "excellent, affordable health insurance," and a "pension plan with early retirement options," I couldn't help imagining myself as an action hero. I became obsessed with the idea, wildly optimistic. It didn't matter that I was 44 years old and had never held a handgun. Here I was, reasonabl...
