in 1965 (one year out of high school, if it had been me). I entered the field in the early 1970s just as he left. My interests in REM sleep and brainstem mechanisms have been eerily similar to his (and he also did po- doctoral work at UCLA), so our research contributions can be distinguished easily only by my use of my middle initial (which has occasionally been om- ted from my publications). So, my namesake and I both have an interest in seeing to it that no one ¿brings shame to the name. ¿ The current work certainly fulfills that dictum. This is a very unusual book, both in its scope and in its approach to the - terial.
